Description:
------------
functions ucfisrst ... strtoupper and so on
do not convert case of non-latin chars in utf8 string i.e. if setlocale (en_US.utf8).
In my script i want to convert case of cyrillic chars.
i'm using ru_RU.utf8 (it doesn't metter en_US or ru_RU.. according to glibc locale all of them use the same table of conversion... i checked both).
i looked through the source of those functions and there are
byte-by-byte convertion of chars... of course it won't work
for utf-8.

You need to use mbstring string functions, which are 
documented at http://www.php.net/mbstring/. All other 
string functions in PHP are byte based, meaning that they 
won't work (properly) with multibyte strings.
