Tracks in Hebrew font not visible

I got a few Hebrew songs transfered from a PC with Windows XP into iTunes on my Mac. But unfortunately - except one name of an artist - the fonts are not in Hebrew but in gibberish characters (not even Latin).

I would like to solve this problem and see the Hebrew characters as Hebrew and not any other language. I guess a similar problem exist also with other non-Latin fonts, such as Cyrillic, Arabic, Japanese, etc..

I tried this, but without luck:

To reverse the Unicode characters:

Select the song and choose Advanced > Convert ID3 Tags.

Command-click to select multiple songs.

Click Translate Text Characters, and then choose Reverse Unicode.

And i also tried:

To change the format of the song information tags:

Select the songs you want to convert.

Choose Advanced > Convert ID3 Tags.

Choose an ID3 version from the pop-up menu.
