[TYPO3] realurl:transiterate ukrainian-cyrillic letters to latin

[Бойчук Петро]

Hello list,
my problem is that i create sites in Ukrainian language (titles and
content are in Ukrainian) and I use realurl for user friendly url's,
bit it transliterates ukrainian letters to latin rules for russian
language.
I want to make realurl to do the same for ukrainian language.
Does anyone know how to create custom rule for ukrainian language?

Thank you.
