I got Korean to display system wide on my N9 out of luck!
It works everywhere from what I can tell. Skype chat, web browser, Facebook app, Music/Video player etc.
Basically, you just have to copy one Korean-capable ttf file into /usr/share/fonts directory.
1. I used 1 Korean TTF font file that was compatible with Nokia Symbian phones.
2. I connected to N9 via ssh/sftp client. (N9 has ssh server built-in and enabled by default)
3. Copied the file into /use/share/fonts/ directory
4. Reboot the phone
(without a reboot, it uses it still but not in some parts such as the web browser)
I have no idea how it just decides to use that font instead of others but hey, I’m not complaining!
Big thanks to cepiperez @ meego forum for the font directory location.
Now all I need is Korean input support and I’ll be VERY happy.
UPDATE: Korean input (native keyboard) & font is now available to install from this article!!
