Well. 3 fonts.
One contains chars used to render time text
One is used to render seconds smaller than time text.
The last one is for info text rendering which contains the most chars from basic ascii to Chinese characters(tens of).
If I turn off anti-alias, it will save a few kBs. But the result really looks ugly. LOL
