I have a simple question - what is the difference between UTF-8, UTF-16 and UTF-32? I know that encoded strings have different sizes, but what is the UTF-16 and UTF-32 for?Should't UTF-8 be able to handle all languages correctly? And how does UTF-7 fit into this?

EDIT

Ok, I relatively understand the technical side of the whole thing, but I still don't see a reason why I should use for example UTF-16 instead of UTF-8 in my app. So my question is - what is the practical usage of other encodings then UTF-8?
