Unknown keysym 'endash' in fr-bepo

[Artefact2]

I am running Arch Linux with kbd 2.4.0.

Trying to load fr-bepo.map with loadkeys prints the following error message.

unknown keysym 'endash'
lk_add_key called with bad keycode -1

The key map still gets applied, but because the return code is 1, this makes some parts of the early boot process (everything that depends on systemd-vconsole-setup.service) fail.

The symbol is in the map file as a U+xxxx sequence, and it seems that they all fail to load.

@Artefact2 endash is not used in any keymap in kbd. I just tried to load the fr-bepo.map and didn't get any errors.

Please attach the fr-bepo.map you are using. It looks like this keymap has been modified or some other add-on is trying to load along with this keymap.

Hi @legionus and thanks for the reply.

My fr-bepo.map is the same as yours, I get the same error regardless:

Try to search the endash in the your /usr/share/kbd (I hope I found the correct source package in archlinux).

Trying to investigate the issue further. The issue happens while trying to parse U+2013 (endash), the first UNUMBER listed in the fr-bepo map. It gets converted to endash in convert_code() but then fails to convert back when calling ksymtocode(). Because the direction is TO_8BIT, the cp1250 charset (that contains endash) is not scanned.
