Not displaying characters with tones in systemd boot menu properly

[peigongdsd]

The latest version of nixos is named 24.11.20240526.a457dae (Vicuña), while the character ñ of Vicuña is not properly displayed in systemd-boot shipped with lanzaboote. See the latest entry in the following image.

I don't believe this is a lanzaboote issue. On my system, the character is displayed correclty. It suspect this might be an issue in your UEFI implementation (or less likely a bug in systemd-boot).

I confirmed this works out of the box on my:

UEFI 2.80 (American Megatrends 5.26)

system.

i.e. the fonts are available on modern up-to-date UEFI.

@nikstur We could consider implementing a "my firmware is bad" mode to strip accents and so on, to be honest.

So I think this is not the right place to ask help for this problem. Maybe I should turn to systemd-boot?

[RaitoBezarius]

systemd-boot is not responsible for this, neither. This is an OEM problem with your firmware. You should contact your PC manufacturer and ask them to push a firmware update that includes a font with those glyphs.

The problem with these workarounds is that there's endless things we could address with hardly any ability to test it.

[RaitoBezarius]

Well, here, the test is pretty trivial, you take EDK2, remove the font that contains a certain glyph, boot and observe garbled output, the test can confirm that we ASCII-ify things or whatever.
