How to discover missing fonts?

NightMonkey · Post by **NightMonkey** » Sat Jul 16, 2022 5:39 pm

Howdy. Let's say I see 'missing glyph' rectangles when I'm using an application in Xorg using Fluxbox. Could be in Xscreensaver, or in a terminal application, for example. How can I find out which missing font the application is trying to use? Is there a 'one-stop-shop' utility or discovery pattern that I can use?

Thanks!

you could install media-fonts/fontawesome or media-fonts/nerd-fonts

do you see a number inside the rectangle :

Code: Select all

fc-match -s monospace:charset=f796 | head -n3

Hack Regular Nerd Font Complete Mono Windows Compatible.ttf: "Hack NF" "Regular"
DejaVu Sans Mono Nerd Font Complete Mono Windows Compatible.ttf: "DejaVuSansMono NF" "Book"
Roboto Mono Nerd Font Complete Mono Windows Compatible.ttf: "RobotoMono NF" "Regular"

If you can copy that missing rectangle glyph, you can search it on fileformat.info, there's a link "fonts that support"

Example: https://www.fileformat.info/info/unicod ... /index.htm

Thanks. I have fontawesome, but 'nerd-fonts' doesn't seem to be in the official portage. Is it in an overlay?

Thanks for this! I can't see a way it would work with XScreensaver text, but it should work for everything else.

yes, look here: https://gpo.zugaina.org/Search?search=nerd-fonts

if you than click on, e.g. media-fonts/nerd-fonts than you'll see on which overlay it's available.

add the overlay via eselect repository

Thank you! One last question - are any of the four listed overlays better maintained than others here?

Is there a rubric for deciding which to select?

you're welcome

i use gentoo-zh!

but, be careful by just adding an overlay, it can jumble with gentoo ebuilds.

you can just copy the nerd-font ebuild to an local overlay or

look here for a mini howto at the end of this thread regarding overlays https://forums.gentoo.org/viewtopic-p-8 ... ml#8658729

have fun
