So, I tried something similar to what I had in mind and was able to get it working. I'll put it here in case anyone wants it:
##### ORIGINAL CODE ##### highlight: function(value, term) { return value.replace(new RegExp("(?![^&;]+;)(?!<[^<>]*)(" + term.replace(/([\^\$\(\)\[\]\{\}\*\.\+\?\|\\])/gi, "\\$1") + ")(?![^<>] *>)(?![^&;]+;)", "gi"), "<strong>$1</strong>"); } ##### MODIFIED CODE WITH ACCENTS-INSENSITIVE SUPPORT ##### highlight : function(value, term) { // Strip accents from 'term' for an accents-insensitive search term = stripAccents(term); var value_no_accents = stripAccents(value); var everything_except_term = value_no_accents.split(new RegExp(term, "gi")); var highlighted_value = ''; var current_position = 0; for (var n in everything_except_term) { // Get the part with accents, since they were stripped to make the comparisson using RegExp, and add it to the final value var part_no_accents = everything_except_term[n]; var part = value.substr(current_position, part_no_accents.length); //--- this one with accents!!! highlighted_value += part; // Add the part length to the current position current_position += part.length; // If its not the last part, add the accented and highlighted term to the final value if (n < everything_except_term.length - 1) { // Get the term with the original accentuation and add it highlighted to the final value var termo_local = value.substr(current_position, term.length); highlighted_value += "<strong>" + termo_local + "</strong>"; // Update the current position current_position += term.length; } } return highlighted_value; } Where the function to strip accents (Credits: http://scripterlative.com/?noaccent) is: function stripAccents(str) { var rExps=[ {re:/[\xC0-\xC6]/g, ch:'A'}, {re:/[\xE0-\xE6]/g, ch:'a'}, {re:/[\xC8-\xCB]/g, ch:'E'}, {re:/[\xE8-\xEB]/g, ch:'e'}, {re:/[\xCC-\xCF]/g, ch:'I'}, {re:/[\xEC-\xEF]/g, ch:'i'}, {re:/[\xD2-\xD6]/g, ch:'O'}, {re:/[\xF2-\xF6]/g, ch:'o'}, {re:/[\xD9-\xDC]/g, ch:'U'}, {re:/[\xF9-\xFC]/g, ch:'u'}, {re:/[\xD1]/g, ch:'N'}, {re:/[\xF1]/g, ch:'n'} ]; for(var i=0, len=rExps.length; i<len; i++) str=str.replace(rExps[i].re, rExps[i].ch); return str; } I'll send and e-mail to the plugin creator suggesting the inclusion of an "ignoreAccents" option, which would toggle beetwen the original and the modified code. That's it. Thanks again for the help!
