I'm thinking about using DejaVu font to create a [Ruby-like][1] font for CJK scripts.
However I'm not sure, does DejaVu provide/support CJK glyphs? Otherwise is there another reusable free/open font you recommend?
The wiki Plan page talk about reusing others work :
CJK - best would be to reuse others work
The status document about language coverage indicate that's there is no glyph for CJK:
