For font subsetting, create a document which contains all symbols that this library can output #603
Description
There is after all not much point in having a font with more symbols than that.
The easiest is to just take all symbols defined in symbol.rs.
We have to be a bit careful though. The document also needs to include:
- all ASCII characters
- all common variation of Latin letters
- Greek letters
- Cyrillic? (the math fonts might not actually have this)
- all math variants (i.e., calligraphic, italic, etc.) for all characters that have math variants
- all size variants
- this might be difficult
- will the font subsetting library take care of this?
