adding new letters to memberlist.php

[kh99]

I realize that you were getting the letters displayed correctly. I don't know a whole lot about using different char encodings but it seems like the code you have is using extended ascii values which aren't always the same (your display changes didn't display hebrew characters when I tried it on my test server, but the code I posted above does). So my thought was that maybe if you instead used html entities for those characters then the search code might work. But like I said, it was just a guess.
