The font is lacking Greek characters, as opposed to a picture in the README

I'm using Nerd-patched Lilex and it doesn't have Greek letters in it: couldn't find them in Gucharmap, and dwm's rendering shows me that the font lacks these glyphs (it draws glyphs from non-default fonts in a smaller size).

I wondered if that's an issue on the Nerd's side, but no: the test page also shows that the font lacks Greek letters

Indeed, something had gone wrong with them. I'll take a closer look tomorrow and try to fix it

Turns out I misunderstood the IBM Plex description. I thought they claimed support for Cyrillic, Latin and Greek for all 3 fonts (Sans, Serif and Mono), but that is not the case. IBM Plex Mono does not support Greek.

But I don't like to lie, and if I claim support, I should add it. There will be Greek support in the 2.500 release!
