The only way right now to change it is download the 0.6 source (the 0.7 source isn't available I don't think), and use the PAlib tutorials to figure out how to change the font and then compile it.
As some of you have already noticed, a Japanese guy called Hashimoto rigged up a way to kinda display Japanese text in a DSLua script.
(His file "putfont.zip" contains "putfont.lua" script)
http://hashimo.ddo.jp/putfont.zipIn the essence, his script converts a Japanese character from a font set into a graphic and draw it on the graphic background.
It is possible, but takes a lot of time.
With alphabetical language, though, the conversion-draw process should be much easier.
You have fewer characters to play with...

I'm not sure this tech would help manu62300. Just an option.
