Missing charset in phpmyadmin. What to do?

A friend asked me to add a php dynamic panel in his site whitch is generated by sum web based site generator. I am bulgarian and we use cp1251 edncoding whitch is Cyrillic Windows. But the site is generated with iso-8859-5 charset and is inpossible to convert it. If I use different cyr charset there are only question marks displayed in the page. And this encoding iso-8859-5 does not exsits in phpmyadmi开发者_JS百科n. Give me please some advise what to do. Thank you very much.

I've manage somhow to change it to utf-8 and it's fine now
