Missing glyphs (.notdef) #15

Closed guillem-catala closed 6 years ago

guillem-catala commented 6 years ago

Hi I love this library! I have a question, is there any way to know if a glyph is missing? Some fonts have chars that are not designed and are usually represented by an square or empty space.

There is an agreement, that when some glyph is not defined, the font should map it to the glyph zero (which is usually a square).

So you can call Typr.U.codeToGlyph(font, charCode), and if it returns zero, the glyph is missing.
