Sorry for a trivial Answer but it looks like you asked for it — look at your Question. Can anyone understand what exactly you need? It's not obvious to me that you understand it yourself, but it looks like you're confused about how Unicode works.

So — http://unicode.org/
]. You will find everything. If something is not clear, please ask another Question.
