Yeah, I was using those already because they are in plane 0 and were
already accessible in Cuis. I wonder if there is some sort of standard
table for these mappings and if all TTF fonts do the same.

Cool, thanks!!

If you mean “together” in the Browser, maybe we can move Utf8String,
Utf32String and UnicodeCodePoint to the category ‘Kernel-Text’ together
with String and Character.

I noticed the image grew about 100MB after loading DejaVu Sans. Now we’re
loading all glyphs. But I don’t think this is going to be a problem for me
because I can easily remove all the glyphs I don’t use in my image (the
vast majority of them). We are not storing redundant contour data for all
the code points that don’t have a glyph like 16r1D53A, right? I took a
quick look at the instance of TTFontDescription and there seems to be data
for this code point, but probably I made a mistake because I’m not familiar
with this…
