Depending on what you mean by speaking unicode; the mbstring extension
has worked well for everything I've ever needed to do with unicode, and
supports all the various unicode character sets.

I believe that string array keys are treated as binary strings, and
never modified. I couldn't find you a source, but I've always worked on
this assumption and never hit a problem. UTF-8 keys definitely work fine
(*); I'm also not aware of any max length the keys can have (meaning you
shouldn't have to worry about a multi-byte character getting truncated
in the middle).

Japanese, Chinese, Arabic and European languages :-)
