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. > So - I was just wondering - when unicode characteres aare used in > array key - does PHP strips them or affects them in any way? 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).
