Hi everyone, under default settings, the fontloaders discards all glyph names which are considered "crappy", meaning matching the "p_crappyname" pattern in "font-oup.lua". For some names this makes a lot of sense. For example the name "uni0303" is considered "crappy" and it really provides no useful information. Then there are other names like "t_uni0303" which are still considered "crappy" while they actually aren't completely useless. So I think there would be some value in preserving them. Of course, you can always enable "otf.keepnames" if you need names like this. But I actually want to talk about another class of names: Look at "Udotbelow". This is IMHO a perfectly normal and useful name, but the fontloader still considers it "crappy" because it starts with a "U" followed by a letter which could be a hexadecimal number. I think this is a bit over-agressive. Maybe the "p_crappyname" pattern could be changed to only look for "u<hexadecimal>" if followed by "p_done", marking the end of a component?
