jquery - open javascript library to do the same thing as symbolset -

i planning on creating own symbol font use on website , had intended on using ligatures , ot support spotty @ best, , non-existant older browsers, ie (i know, big surprise). started taking close @ how symbolset works. it's pretty clever , while easy me change couple array variables , done it, javascript proprietary , can't use without permission. i'd love able create own symbol fonts la symbolset i'd need open javascript file let me this. there open jquery plug-ins or javascript libraries this?

i have found http://labs.adamdscott.com/ligatures/ligaturejs.html. walks dom, , replaces known letter combinations ligatures. i've modified script use native ligature support when available:

// ligature.js v1.0 // http://code.google.com/p/ligature-js/  // modifications sabof  var ligature = (function() {   var testdiv = document.createelement('div'),        nativeligaturesupport = testdiv.style.textrendering !== undefined;   if (nativeligaturesupport) {     return function (node, extended) {       if (!node) {         ligature(document.body, extended);       } else {         node.style.textrendering = 'optimizelegibility';       }     }   }   return function(node, extended) {     if (!node) {       ligature(document.body, extended);     } else {       if (node.nodetype == 3 && node.parentnode.nodename != 'script') {         node.nodevalue = node.nodevalue           .replace(/ffl/g, 'ffl')           .replace(/ffi/g, 'ffi')           .replace(/fl/g, 'fl')           .replace(/fi/g, 'fi')           .replace(/ff/g, 'ff')           .replace(/ij/g, 'ij')           .replace(/ij/g, 'IJ');          if (extended) {           node.nodevalue = node.nodevalue             .replace(/ae/g, 'æ')             .replace(/a[ee]/g, 'Æ')             .replace(/oe/g, 'œ')             .replace(/o[ee]/g, 'Œ')             .replace(/ue/g, 'ᵫ')             .replace(/st/g, 'st');         }       }       if (node.childnodes) {         (var i=0; < node.childnodes.length; i++) {           ligature(node.childnodes.item(i), extended);         }       }     }   };  }());
