Can Not See What The Language is on the Mozilla's Menu

Hi!

I like to test software before burning it into a CD.
I run the KNOPPIX_V3.3-2004-02-16-EN.iso under MS-Virtual PC 2004.
Everything is ok including network functions. However, the mozilla's menu shows strange language that I can not understand. I know what the supposed item according to a location in a mozilla's menu should be. But, everthing (should be English) including what I input in a form (search engine) is not showed correctly. In other words, I can not recognize what I inputed in a form...

Why ?

Sincerely
