There's a couple subclasses for 8bit fonts or (incorporating geometry structs) character-ID fonts, both adding additional properties.
You can ask fonts for their location, returning an enum for whether the font's embedded, the font's encoding, Ref to the font in the file, filepath, ID in the fontfile, & a fallback font index.
The implementation is, beyond the usual heavy focus on parsing & accessors, implements set operations upon charsets & lookups of built-in fonts.
