translated strings bad encoding

[Migrated From Jforum.net]

I started translating JForum to Polish and have problem with encoding translated strings from pl_PL.properties. I tried UTF-8 and ISO-8859-2 and both don't work properly. I'm sure that pl_PL.properties encoding is the same as that I set in Admin Control Panel. Posts encoding works fine. Is this a new bug or I make somethink wrong?

I use UTF-8 system (forum) encoding and I had to use unicode hex entities instead of diacritics. It has one big advantage - you don't have to specify the encoding of properties file and It will work on all platforms. I use PSpad editor for transcoding national characters to unicode hex entities.

Thx for reply. I think I found the reason of the problem. I18n class use java.util.Properties to store strings from properties files. According to javadoc Properties use ISO-8859-1 encoding which is not capable to encode Polish chars.
