Cool! Thank you! It really works and non-latin characters are
displaying the way they should.

But I cann't understand, how TYPO "knows", which part of string in array
refers to which language?
For example, where I can define, some kind of this:
russian|english|german|some_another_language||||||||
Now I have such setting:
"1" => array ("Лево верх|Left|||||||||","1"),
"0" => array ("Право|Normal|||||||||","0"),
"3" => array ("Лево низ|Border|||||||||","3"),
And the first russian part displays everytime, and it doesn't care,
which language BE user has at his settings.
