Confusion about Utf8TruncateToLength and company

@ab - I use a function

Utf8TruncateToLength('Обрізати до 10 літер', 10);
// expect 'Обрізати д'
// but actual 'Обрі'

and expect result to be truncated to 10 UTF8 characters, but actual result is truncated to ~10 bytes.

Is it valid behavior?
If yes, then my propose is to change UTF8*Length functions documentation (and the name of parameter maxUTF8 -> maxBytes)
because current documentation is confused...

It is truncated to equal or less than 10 bytes IIRC.
