Hi, I recently set up Linux (Debian to be precise) on a new laptop with a high resolution display. I'd like to increase the font size in Grub (v2.12) and opted to just use a custom font as the default font "GNU Unifont Regular" (at least on Debian it is) does have a OTF version, but seems to look jagged by design, but I'm running into issues. I thought about just using Noto Mono Regular for it, as Noto is supposed to always work and a monospaced font seems to be recommended for easier setting of letters, as Grub uses bitmap fonts. Now my issue is that on one hand, the conversion to a bitmap font seems to be quite bad, the letters look really jagged. Also, it seems that despite Noto supposed to being about no tofu, I actually get a lot of tofu. Both the up and down arrows in the description text at the bottom of grubs boot selector and the border around everything is just made up of tofu. Just scaling GNU Unifont Regular does remove the issue of tofu but the font will always look jagged no matter what. I tried converting Noto with both grub-customizer and with grub-mkfont, both with only -s 20 and with -as 20, same result.
So what exactly are the requirements for fonts to be used in Grub so that they are converted to PFF2 fonts in a higher quality and don't show tofu? There seems to be a range option in grub-mkfont. Do I need to use it? And how would I need to define the range? My expectation would be that grub-mkfont by default would include all symbols needed to display the default boot menu so I kind of doubt defining a range would be needed. Best Richard
