If you have missing glyphs (Emoji in particular) in #Lagrange, this may help: https://git.skyjake.fi/gemini/font-library/src/branch/main/build/get_symbola.sh

It's a shell/Python script that downloads Symbola from UFAS and converts it to TrueType (using "fonttools"). You can then drag-and-drop the .ttf on the Lagrange window to install it.

(Requires python3 and pip3.)

Symbola is quite a nice Unicode 13 compatible font, but available only for personal use so I can't put it in the Font Library.
