Remove accents on search for other languages

[Victor-arias]

In Spanish there are letters with accents (tildes), when looking for an accented word without the right accent the word is discarded.

For example in spanish the action word is written as "acción", that is not equal to "accion".

I use a Javascript function would appreciate inclusion in this wonderful library.

function accentsTidy(s){
  var r = s.toLowerCase();
  r = r.replace(new RegExp("[àáâãäå]", 'gi'),"a");
  r = r.replace(new RegExp("æ", 'gi'),"ae");
  r = r.replace(new RegExp("ç", 'gi'),"c");
  r = r.replace(new RegExp("[èéêë]", 'gi'),"e");
  r = r.replace(new RegExp("[ìíîï]", 'gi'),"i");
  r = r.replace(new RegExp("ñ", 'gi'),"n");                            
  r = r.replace(new RegExp("[òóôõö]", 'gi'),"o");
  r = r.replace(new RegExp("œ", 'gi'),"oe");
  r = r.replace(new RegExp("[ùúûü]", 'gi'),"u");
  r = r.replace(new RegExp("[ýÿ]", 'gi'),"y");
  return r;
}

Thank you.
