First of all, for this to work, you need xterm and know how to become root. (see http://maemo.org/maemowiki/HowTo_EASILY_BecomeRoot) Also, to save internal flash memory, the font will be placed on the memory card.

Here are the steps:

1. Download the true type font from maemocjk's subversion repository:
   • use browser to go to https://garage.maemo.org/plugins/scm...?root=maemocjk
   • select ttf-arphic-ukai-0.1.20060513-maemo/ (versioen number might
     change)
   • select ukai.ttf
   • select to download.
   • save font to memory card. For example in the subdirectory fonts. (Below I assume that ukai.ttf is downloaded to /media/mmc1/fonts/)
2. start xterm and become root
3. type:
   
   Code:

   cd /usr/share/fonts
   ln -s /media/mmc1/fonts/ukai.ttf .
   fc-cache -fv

4. wait for fc-cache to finish
5. reboot device
