It is because of the engine developers does not feel a difference between the strlen() and mb_strlen() functions,
and most of translators does not feel a difference between bytes and characters.

The original "username" database field length is only 15 bytes;
Multilingual version expands it to 64 bytes, so it is possible to enter about 20~32 multi-byte characters.
The problem is only in the length verification algorithm.
It requires the username length must be not longer than 15 bytes.

It is a reason to patch this algorithm co calculate the length in characters....

I have digged the problem.
Javascript can calculate a string length only in CHARACTERS.
And Javascript can NOT calculate an UTF-8 string length in BYTES.

The beautifull O'Reilly explain me how JS store characters in UTF-16,
and give me an idea how to count the byte-length for UTF-8 strings.
I have wrote a JS function "utf8length()" and now testing it.
If the test will ok, I'll integrate this function into iX2.
