How can I retrieve the name of a given character in VB .NET (2005)?

I'm wondering how to get the 'official name' of any given character retrievable with the ChrW() function. For example, if I input 'A' (or perhaps just 65), I'd get something like "Latin Capital Letter A" as the output. I'm not even sure if there is a list of these definitions accessible in some API function or something, or if programmers insert this information themselves. Please help!
