I’m working on the too big glyphs. This only appears when high‐detail
glyphs, like Japanese or Chinese are scaled down.


Try this in current st please. It works! :D

There is a new patch in st, which should speed the drawing back to nor‐
mal speed, when you are only using known characters from your font. It
will need some time, when you first access unknown characters.

I need some hints of people using many different Unicode subsets, if a
cache of 256 characters is enough.

I’m working on the bugs in the selection code related to wrong back re‐
porting of glyph widths.
