Support special characters

Special character cases should be aknowledged in the javascript-file. For example I needed a quote, so I added

var first_letter = text.substr(0,1);
if(first_letter == '"') first_letter = 'quote';

into line 15 of dropcap.js.
Maybe there should be an array which converts special characters into names, i.e. " = quote , - = 'dash', etc...
