Oh. I encode the more stable glyphs. This saves me about 40% of the size. Allows me to ship all the fonts in a package less than 100K. That is an optional detail. The main software works with either encoded or decoded.
There IS a function to do the encoding/decoding, obviously. I think both directions are in the main code module.
If you go to Comic Sans font file and look at lowercase “j” you will see all versions. The output from the glyph inspector (sortof), the unencoded MeshWriter format and the encoded MeshWriter format.
