Where the font came from, and when

https://github.com/googlefonts/noto-fonts/blob/2a41389346abdb6b83f5e0c4efe598bcb8abbb42/phaseIII_only/unhinted/ttf/NotoSerifTibetan/NotoSerifTibetan-Regular.ttf

Issue

While debugging https://github.com/fontforge/fontforge/issues/3740, I noticed that the font has many glyph names in the post table that are not used.

The font has 1891 glyphs, while there are 3772 names in the post table (as seen in the ttx dump).

While this is not strictly a bug, it seems wasteful to include such unused data. It might also indicate an issue in the sources or the font generation pipeline.

It has the production names AND the non-production names in there. That sounds like an issue with the fontmake pipeline because it should be either --no-production-names or it uses them. That post table looks like a mix.

Bug in ufo2ft, will fix there.
