The question doesn't make sense. The UTF-8 encoding can encode any character in Unicode, in other words any character you can have in your Java code. So if you're asking "What fonts can render the entire Unicode character set" then the answer is probably "There aren't any".
Anyway fonts are generally associated with scripts, not encodings. Where did this question come from?

the question comes with the problem: displaying special character into a PDF using iText, it can't display those characters even if i'm using the UTF-8 encoding type wich in theory, support those characters...
