ID3 tag information in Russian

Hi,
I purchased the sansa e250 mp3 player. I updated to the new firmware.
It doesn’t read ID3 tag information (like album, artist…) in Russian, instead of Russian it shows unidentified letters. All it reads (you can see Russian letters) in Russian is the name of the file.
Please help me fixing this problem.

Thanks.

You need the European firmware for Russian support…

What firmware do you have?
