Jquery Mobile on Android - trouble with Cyrillic auto-complete

I'm trying to perform autocomplete with Cyrillic and English data.

If I type some search text in English everything is fine (except overall开发者_开发技巧 speed of jQuery on Android), but when I try to search for something in Russian or Ukrainian the phone sticks.

How does a phone stick?

Ok, seriously - See if this has to do with encoding. Maybe at some stage you didn't define encoding as utf-8. Be sure to do it in HTML head and on the server side.

[edit]

The problem seems to be with keypress event.

After you preform tests I suggested (running on desktop webkit and checking if keypress is triggered at all in android) report back and I will be able to help and fill in this answer
