$ ls -lh system/fonts/I tried to install some of them to my Windows XP PC.

Just copy them to SD card, then drag & drop into c:\Windows\Fonts.
So, the biggest font file, DroidSansFallback.ttf, has Japanese font in it. I guess other language fonts such as Simple Chinese and Big5 also supported by this single font file as well as other European Language fonts.
It's like a zipping the World into 3M bytes. I'm not fammiliar with embedded font things, but I guess Android has one of the most sophisticated font systems.
This is only an experiment. Copying out the font files may bring up copyright issue, so I deleted them from my PC.
