Allocate fallback fonts on the heap
...
The size of a font is quite large ~ 100KB so it does not make sense to
store their data statically.

Better fix for not using the unsafe to break flag
...
Recognize special glyphs by comparing the index to the glyph for the
codepoint in the font. Cannot rely on glyph width as many glyphs have
zero width. For example the glyph for space characters.

Use fc-list instead of fc-match to select fonts
...
This is because there is no way to force fc-match to return a monospace
font. So if the user specifies a non-existent font we end up with some
non-monospaced font, which looks terrible.
Also, this makes the font selection logic or macOS and Linux similar.
