¿Reemplazar eficientemente todos los caracteres acentuados en una cadena?

Question

¿Reemplazar eficientemente todos los caracteres acentuados en una cadena?

Para la implementación de un hombre pobre de cerca de-intercalación-ordenación correcta en el lado del cliente Necesito una función JavaScript que haga reemplazo eficiente de un solo carácter en una cadena.

Esto es lo que quiero decir (tenga en cuenta que esto se aplica al texto alemán, otros idiomas ordenar de manera diferente):

native sorting gets it wrong: a b c o u z ä ö ü
collation-correct would be:   a ä b c o ö u ü z

Básicamente, necesito que todas las ocurrencias de "ä" de una cadena dada sean reemplazadas por "a" (y así sucesivamente). De esta manera el resultado de la ordenación nativa sería muy cercano a lo que un usuario esperaría (o lo que una base de datos devolvería).

Otros lenguajes tienen facilidades para hacer precisamente eso: Python supplies str.translate(), en Perl hay tr/…/…/, XPath tiene una función translate(), ColdFusion ha ReplaceList(). Pero, ¿qué pasa con JavaScript?

Esto es lo que tengo ahora mismo.

// s would be a rather short string (something like 
// 200 characters at max, most of the time much less)
function makeSortString(s) {
  var translate = {
    "ä": "a", "ö": "o", "ü": "u",
    "Ä": "A", "Ö": "O", "Ü": "U"   // probably more to come
  };
  var translate_re = /[öäüÖÄÜ]/g;
  return ( s.replace(translate_re, function(match) { 
    return translate[match]; 
  }) );
}

Para empezar, no me gusta el hecho de que la expresión regular se reconstruye cada vez que llamo a la función. Supongo que un cierre puede ayudar en este sentido, pero no me parece para cogerle el truco por alguna razón.

¿Puede alguien pensar en algo más eficiente?

Las respuestas a continuación se dividen en dos categorías:

Funciones de reemplazo de cadenas de diferentes grados de integridad y eficiencia (lo que estaba preguntando originalmente)
A mención tardía de String#localeCompare, que es ampliamente compatible entre los motores JS y podría resolver esta categoría de problema mucho más elegantemente.

La terminología correcta para tales acentos es Diacríticos. Después de buscar en Google este término, encontré esta función que es parte de backbone.paginator. Tiene una colección muy completa de diacríticos y los reemplaza con su carácter ascii más intuitivo. Encontré que esta es la solución Javascript más completa disponible en la actualidad.

La función completa para referencia futura:

Basado en la solución de Jason Bunting, esto es lo que uso ahora.

Todo es para el complemento jQuery tablorter: Para la clasificación (casi correcta) de tablas no inglesas con el complemento tablorter es necesario hacer uso de un complemento personalizado textExtraction function .

Este:

traduce las letras acentuadas más comunes a las no acentuadas (la lista de letras soportadas es fácilmente expandible)
cambia las fechas en formato alemán ('dd.mm.yyyy') a un formato reconocido('yyyy-mm-dd')

Tenga cuidado de guardar el archivo JavaScript en codificación UTF-8 o no funcionará.

// file encoding must be UTF-8!
function getTextExtractor()
{
  return (function() {
    var patternLetters = /[öäüÖÄÜáàâéèêúùûóòôÁÀÂÉÈÊÚÙÛÓÒÔß]/g;
    var patternDateDmy = /^(?:\D+)?(\d{1,2})\.(\d{1,2})\.(\d{2,4})$/;
    var lookupLetters = {
      "ä": "a", "ö": "o", "ü": "u",
      "Ä": "A", "Ö": "O", "Ü": "U",
      "á": "a", "à": "a", "â": "a",
      "é": "e", "è": "e", "ê": "e",
      "ú": "u", "ù": "u", "û": "u",
      "ó": "o", "ò": "o", "ô": "o",
      "Á": "A", "À": "A", "Â": "A",
      "É": "E", "È": "E", "Ê": "E",
      "Ú": "U", "Ù": "U", "Û": "U",
      "Ó": "O", "Ò": "O", "Ô": "O",
      "ß": "s"
    };
    var letterTranslator = function(match) { 
      return lookupLetters[match] || match;
    }

    return function(node) {
      var text = $.trim($(node).text());
      var date = text.match(patternDateDmy);
      if (date)
        return [date[3], date[2], date[1]].join("-");
      else
        return text.replace(patternLetters, letterTranslator);
    }
  })();
}

Puedes usarlo así:

$("table.sortable").tablesorter({ 
  textExtraction: getTextExtractor()
});

Creo que esto podría funcionar un poco más limpio / mejor (aunque no he probado su rendimiento):

String.prototype.stripAccents = function() {
    var translate_re = /[àáâãäçèéêëìíîïñòóôõöùúûüýÿÀÁÂÃÄÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ]/g;
    var translate = 'aaaaaceeeeiiiinooooouuuuyyAAAAACEEEEIIIINOOOOOUUUUY';
    return (this.replace(translate_re, function(match){
        return translate.substr(translate_re.source.indexOf(match)-1, 1); })
    );
};

O si todavía estás demasiado preocupado por el rendimiento, vamos a obtener lo mejor de ambos mundos:

String.prototype.stripAccents = function() {
    var in_chrs =  'àáâãäçèéêëìíîïñòóôõöùúûüýÿÀÁÂÃÄÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ',
        out_chrs = 'aaaaaceeeeiiiinooooouuuuyyAAAAACEEEEIIIINOOOOOUUUUY', 
        transl = {};
    eval('var chars_rgx = /['+in_chrs+']/g');
    for(var i = 0; i < in_chrs.length; i++){ transl[in_chrs.charAt(i)] = out_chrs.charAt(i); }
    return this.replace(chars_rgx, function(match){
        return transl[match]; });
};

EDIT (por @Tomalak)

Aprecio la idea. Sin embargo, hay varias cosas incorrectas con la implementación, como se describe en el comentario a continuación.

Así es como lo implementaría.

var stripAccents = (function () {
  var in_chrs   = 'àáâãäçèéêëìíîïñòóôõöùúûüýÿÀÁÂÃÄÇÈÉÊËÌÍÎÏÑÒÓÔÕÖÙÚÛÜÝ',
      out_chrs  = 'aaaaaceeeeiiiinooooouuuuyyAAAAACEEEEIIIINOOOOOUUUUY', 
      chars_rgx = new RegExp('[' + in_chrs + ']', 'g'),
      transl    = {}, i,
      lookup    = function (m) { return transl[m] || m; };

  for (i=0; i<in_chrs.length; i++) {
    transl[ in_chrs[i] ] = out_chrs[i];
  }

  return function (s) { return s.replace(chars_rgx, lookup); }
})();

Simplemente se debe normalizar la cadena y ejecutar un código de reemplazo:

var str = "Letras Á É Í Ó Ú Ñ - á é í ó ú ñ...";
console.log (str.normalize ("NFKD").replace (/[\u0300-\u036F]/g, ""));
// Letras A E I O U N - a e i o u n...

Ver normalizar

Entonces puedes usar esta función:

function noTilde (s) {
    if (s.normalize != undefined) {
        s = s.normalize ("NFKD");
    }
    return s.replace (/[\u0300-\u036F]/g, "");
}

Si está buscando específicamente una forma de convertir caracteres acentuados a caracteres no acentuados, en lugar de una forma de ordenar caracteres acentuados, con un poco de finagling, la cadena.La función localeCompare se puede manipular para encontrar los caracteres latinos básicos que coincidan con los extendidos. Por ejemplo, es posible que desee producir un slug url amigable para humanos a partir del título de una página. Si es así, puedes hacer algo como esto:

var baseChars = [];
for (var i = 97; i < 97 + 26; i++) {
  baseChars.push(String.fromCharCode(i));
}

//if needed, handle fancy compound characters
baseChars = baseChars.concat('ss,aa,ae,ao,au,av,ay,dz,hv,lj,nj,oi,ou,oo,tz,vy'.split(','));

function isUpperCase(c) { return c !== c.toLocaleLowerCase() }

function toBaseChar(c, opts) {
  opts = opts || {};
  //if (!('nonAlphaChar' in opts)) opts.nonAlphaChar = '';
  //if (!('noMatchChar' in opts)) opts.noMatchChar = '';
  if (!('locale' in opts)) opts.locale = 'en';

  var cOpts = {sensitivity: 'base'};

  //exit early for any non-alphabetical character
  if (c.localeCompare('9', opts.locale, cOpts) <= 0) return opts.nonAlphaChar === undefined ? c : opts.nonAlphaChar;

  for (var i = 0; i < baseChars.length; i++) {
    var baseChar = baseChars[i];

    var comp = c.localeCompare(baseChar, opts.locale, cOpts);
    if (comp == 0) return (isUpperCase(c)) ? baseChar.toUpperCase() : baseChar;
  }

  return opts.noMatchChar === undefined ? c : opts.noMatchChar;
}

function latinify(str, opts) {
  return str.replace(/[^\w\s\d]/g, function(c) {
    return toBaseChar(c, opts);
  })
}

// Example:
console.log(latinify('Čeština Tsėhesenėstsestotse Tshivenḓa Emigliàn–Rumagnòl Slovenščina Português Tiếng Việt Straße'))

// "Cestina Tsehesenestsestotse Tshivenda Emiglian–Rumagnol Slovenscina Portugues Tieng Viet Strasse"

Esto debería funcionar bastante bien, pero si se necesitara una optimización adicional, se podría usar una búsqueda binaria con localeCompare como comparador para localizar el carácter base. Tenga en cuenta que las mayúsculas y minúsculas se conservan, y las opciones permiten conservar, reemplazar o eliminar caracteres que no son alfabéticos o que no tienen caracteres latinos coincidentes con los que se pueden reemplazar. Esta implementación es más rápida y flexible, y debería funcionar con nuevos caracteres a medida que se agregan. La desventaja es que los caracteres compuestos como " tienen que ser manejados específicamente, si necesitan ser apoyados.

Https://stackoverflow.com/a/37511463

Con Cadena ES2015/ES6 .Prototipo.Normalizar(),
const str = "Crème Brulée"
str.normalize('NFD').replace(/[\u0300-\u036f]/g, "")
> 'Creme Brulee'
Dos cosas están sucediendo aquí:

normalize() ing a NFD La forma normal Unicode descompone los grafemas combinados en la combinación de los simples. El è de Crème termina expresado como e + ̀.

Usando una regex clase de caracteres para coincidir con el rango U+0300 → U+036F, ahora es trivial para g lobalmente deshacerse de los diacríticos, que el estándar Unicode convenientemente agrupa como el Combinando Marcas diacríticas Bloque Unicode.

Ver comentario para pruebas de rendimiento.

Alternativamente, si solo desea ordenar

Intl.Collator tiene suficiente soporte ~85% en este momento, un polyfill también está disponible aquí pero no lo he probado.
const c = new Intl.Collator();
['creme brulee', 'crème brulée', 'crame brulai', 'crome brouillé',
'creme brulay', 'creme brulfé', 'creme bruléa'].sort(c.compare)
[ 'crame brulai','creme brulay','creme bruléa','creme brulee',
'crème brulée','creme brulfé','crome brouillé' ]


['creme brulee', 'crème brulée', 'crame brulai', 'crome brouillé'].sort((a,b) => a>b)
["crame brulai", "creme brulee", "crome brouillé", "crème brulée"]

Hice una versión prototipo de esto:

String.prototype.strip = function() {
  var translate_re = /[öäüÖÄÜß ]/g;
  var translate = {
    "ä":"a", "ö":"o", "ü":"u",
    "Ä":"A", "Ö":"O", "Ü":"U",
    " ":"_", "ß":"ss"   // probably more to come
  };
    return (this.replace(translate_re, function(match){
        return translate[match];})
    );
};

Use como:

var teststring = 'ä ö ü Ä Ö Ü ß';
teststring.strip();

Esto cambiará la cadena a a_o_u_A_O_U_ss

Un puerto directo a javascript de la solución de Kierons: https://github.com/rwarasaurus/nano/blob/master/system/helpers.php#L61-73 :

      var nonLatin = removalMap[latin];
      str = str.replace(nonLatin , latin);
    }

    return str;
}

Utiliza caracteres reales en lugar de lista unicode y funciona bien.

Puedes usarlo como

"ąąą".removeAccents(); // returns "aaa"

Puede convertir fácilmente esta función para que no sea string prototype. Sin embargo, como soy fan de usar string prototype en tales casos, tendrás que hacerlo tú mismo.

Hace mucho tiempo hice esto en Java y encontré la solución de otra persona basada en una sola cadena que captura parte de la tabla Unicode que era importante para la conversión - el resto se convirtió a ? o cualquier otro personaje de reemplazo. Así que traté de convertirlo a JavaScript. Ten en cuenta que no soy un experto en JS. :-)

TAB_00C0 = "AAAAAAACEEEEIIII" +
    "DNOOOOO*OUUUUYIs" +
    "aaaaaaaceeeeiiii" +
    "?nooooo/ouuuuy?y" +
    "AaAaAaCcCcCcCcDd" +
    "DdEeEeEeEeEeGgGg" +
    "GgGgHhHhIiIiIiIi" +
    "IiJjJjKkkLlLlLlL" +
    "lLlNnNnNnnNnOoOo" +
    "OoOoRrRrRrSsSsSs" +
    "SsTtTtTtUuUuUuUu" +
    "UuUuWwYyYZzZzZzF";

function stripDiacritics(source) {
    var result = source.split('');
    for (var i = 0; i < result.length; i++) {
        var c = source.charCodeAt(i);
        if (c >= 0x00c0 && c <= 0x017f) {
            result[i] = String.fromCharCode(TAB_00C0.charCodeAt(c - 0x00c0));
        } else if (c > 127) {
            result[i] = '?';
        }
    }
    return result.join('');
}

stripDiacritics("Šupa, čo? ľšťčžýæøåℌð")

Esto convierte la mayoría de los caracteres Unicode latin1+2. No es capaz de traducir char simple a múltiple. No conozco su rendimiento en JS, en Java esto es de lejos la más rápida de las soluciones comunes (6-50x), no hay mapa, no hay regex, nada. Produce salida ASCII estricta, potencialmente con una pérdida de información, pero el tamaño de la salida coincide con la entrada.

Probé el fragmento con http://www.webtoolkitonline.com/javascript-tester.html y produjo Supa, co? lstczyaoa?? como se esperaba.

Ni una sola respuesta menciona String.localeCompare, lo que pasa que hacer exactamente lo que originalmente quería, pero no lo que estás pidiendo.

var list = ['a', 'b', 'c', 'o', 'u', 'z', 'ä', 'ö', 'ü'];

list.sort((a, b) => a.localeCompare(b));

console.log(list);

//Outputs ['a', 'ä', 'b', 'c', 'o', 'ö', 'u', 'ü', 'z']

El segundo y tercer parámetro no son compatibles con los navegadores más antiguos. Sin embargo, es una opción que vale la pena considerar.

const base_chars = [

const fix = str => str.normalize('NFKD').split('')
    .map(c => base_chars.find(bc => bc.localeCompare(c, 'en', { sensitivity: 'base' })==0))
    .join('');

const str = 'OÒ óëå-123';
console.log(`fix(${str}) = ${fix(str)}`);

Si desea lograr una clasificación donde "ä" viene después de "a" y no se trata como lo mismo, entonces puede usar una función como la mía.

Siempre puedes cambiar el alfabeto para obtener clasificaciones diferentes o incluso extrañas. Sin embargo, si desea que algunas letras sean equivalentes, entonces tiene que manipular las cadenas como a = a.replace(/ä/, 'a') o similares, ya que muchas ya han respondido anteriormente. He incluido las letras mayúsculas si alguien quiere tener todas las palabras mayúsculas antes de todas las palabras minúsculas (entonces tienes que ommit .toLowerCase()).

function sortbyalphabet(a,b) {
        alphabet = "0123456789AaÀàÁáÂâÃãÄäBbCcÇçDdÈèÉéÊêËëFfGgHhÌìÍíÎîÏïJjKkLlMmNnÑñOoÒòÓóÔôÕõÖöPpQqRrSsTtÙùÚúÛûÜüVvWwXxÝýŸÿZz";
        a = a.toLowerCase();
        b = b.toLowerCase();
        shorterone = (a.length > b.length ? a : b);
        for (i=0; i<shorterone.length; i++){
            diff = alphabet.indexOf(a.charAt(i)) - alphabet.indexOf(b.charAt(i));
            if (diff!=0){
                return diff;
            }
        }
        // sort the shorter first
        return a.length - b.length;
    }
    var n = ["ast", "Äste", "apfel", "äpfel", "à"];
    console.log(n.sort(sortbyalphabet));
    // should return ["apfel", "ast", "à", "äpfel", "äste"]

Una manera simple y fácil:

function remove-accents(p){
c='áàãâäéèêëíìîïóòõôöúùûüçÁÀÃÂÄÉÈÊËÍÌÎÏÓÒÕÖÔÚÙÛÜÇ';s='aaaaaeeeeiiiiooooouuuucAAAAAEEEEIIIIOOOOOUUUUC';n='';for(i=0;i<p.length;i++){if(c.search(p.substr(i,1))>=0){n+=s.substr(c.search(p.substr(i,1)),1);} else{n+=p.substr(i,1);}} return n;
}

Así que haz esto:

remove-accents("Thís ís ân accêntéd phráse");

Salida:

"This is an accented phrase"

No puedo pensar en una manera más fácil de eliminar eficientemente todos los diacríticos de una cadena que usar esta solución increíble.

Véalo en acción:

var string = "öäüÖÄÜ";

var string_norm = string.normalize('NFD').replace(/[\u0300-\u036f]/g, '');
console.log(string_norm);

Lo he resuelto de otra manera, si quieres.

Aquí utilicé dos matrices donde Barras de búsqueda que contiene los que serán sustituidos y Sustitutos contiene los caracteres deseados.

var text = "your input string";
var searchChars = ['Å','Ä','å','Ö','ö']; // add more charecter.
var replaceChars = ['A','A','a','O','o']; // exact same index to searchChars.
var index;
for (var i = 0; i < text.length; i++) {
  if( $.inArray(text[i], searchChars) >-1 ){ // $.inArray() is from jquery.
    index = searchChars.indexOf(text[i]);
    text = text.slice(0, i) + replaceChars[index] + text.slice(i+1,text.length);
  }

No puedo hablar de lo que está tratando de hacer específicamente con la función en sí, pero si no le gusta que la expresión regular se construya cada vez, aquí hay dos soluciones y algunas advertencias sobre cada una.

Aquí hay una manera de hacer esto:

function makeSortString(s) {
  if(!makeSortString.translate_re) makeSortString.translate_re = /[öäüÖÄÜ]/g;
  var translate = {
    "ä": "a", "ö": "o", "ü": "u",
    "Ä": "A", "Ö": "O", "Ü": "U"   // probably more to come
  };
  return ( s.replace(makeSortString.translate_re, function(match) { 
    return translate[match]; 
  }) );
}

Esto obviamente hará que la expresión regular sea una propiedad de la propia función. Lo único que puede que no te guste de esto (o puede que, supongo que depende) es que la expresión regular ahora se puede modificar fuera del cuerpo de la función. Así que, alguien podría hacer esto para modificar la expresión regular utilizada interalmente:

makeSortString.translate_re = /[a-z]/g;

Entonces, existe esa opción.

Una forma de obtener un cierre, y así evitar que alguien modifique la expresión regular, sería definir esto como una asignación de función anónima como esta:

var makeSortString = (function() {
  var translate_re = /[öäüÖÄÜ]/g;
  return function(s) {
    var translate = {
      "ä": "a", "ö": "o", "ü": "u",
      "Ä": "A", "Ö": "O", "Ü": "U"   // probably more to come
    };
    return ( s.replace(translate_re, function(match) { 
      return translate[match]; 
    }) );
  }
})();

Esperemos que esto sea útil para usted.

ACTUALIZACIÓN: Es temprano y no se por qué no vi lo obvio antes, pero también podría ser útil ponerle translate objeto en un cierre también:

var makeSortString = (function() {
  var translate_re = /[öäüÖÄÜ]/g;
  var translate = {
    "ä": "a", "ö": "o", "ü": "u",
    "Ä": "A", "Ö": "O", "Ü": "U"   // probably more to come
  };
  return function(s) {
    return ( s.replace(translate_re, function(match) { 
      return translate[match]; 
    }) );
  }
})();
