After doing some research, I was able to show chinese / japanese fonts on the phone (support font too). I have make modification on Nokia Hindi S60 and Heisei Kaku Gothic S60.
I have 4 fonts here:
nohindisnr60.ttf (Heisei Kaku Gothic S60)
nohindissb60.ttf (Nokia Hindi S60 SemiBold)
nohinditsb60.ttf (Nokia Hindi S60 TitleSemiBold)
S60ZDIGI.ttf (Series 60 ZDigi)
If you prefer simplified kanji, it will costs you about 12 MB space. The attachment in the post #11 here named "Fonts Modified with SimCh":
If you just prefer the basic kanji (about 9 MB after extracting), just continue reading.
You may need to correct the fonts name before transfer to your memory card, what you need is make match to your Z:\resource\fonts (Europa and Asian firmware has different names). The font you'll downloaded here is for Europa firmware, Asian firmware requires modification on its name.
