javascript+remove arabic text diacritic dynamically

Question

how to remove dynamically Arabic diacritic I\'m designing an ebook \"chm\" and have multi html pages contain Arabic text but some time the search engine want highlight so

Answer 1

I wrote this function which handles strings with mixed Arabic and English characters, removing special characters (including diacritics) and normalizing some Arabic characters like converting all ة's into ه's.

normalize_text = function(text) {

  //remove special characters
  text = text.replace(/([^\u0621-\u063A\u0641-\u064A\u0660-\u0669a-zA-Z 0-9])/g, '');

  //normalize Arabic
  text = text.replace(/(آ|إ|أ)/g, 'ا');
  text = text.replace(/(ة)/g, 'ه');
  text = text.replace(/(ئ|ؤ)/g, 'ء')
  text = text.replace(/(ى)/g, 'ي');

  //convert arabic numerals to english counterparts.
  var starter = 0x660;
  for (var i = 0; i < 10; i++) {
    text.replace(String.fromCharCode(starter + i), String.fromCharCode(48 + i));
  }

  return text;
}

Normalize
