Description Ilya Zverev 2023-12-06 10:12:47 UTC
SUMMARY
I chose to use Estonian (US) keyboard layout, because it's easier to use on regular US keyboards. Basically it's the same as us(basic), but it adds additional accented letters with level3 bindings: e.g. to type ä, ü, ö, õ, ž you press Right Alt + a, u, o, q, z. You can see the binding in /usr/share/X11/xkb/symbols/ee (for Fedora Linux).

Instead, for ä and ü I get "́" and "₴". Same for alternative bindings for these letters, RAlt+f, apostrophe, bracketleft. Despite the bindings present in the layout file, they are probably overridden by the default typographic letters for level3 layouts. I can see that on the layout map from the layout chooser in Settings.

So the question is, can this be fixed, or I better modify the layout?

Thankfully I can type all uppercase letters and some of other lowercase, so it works partially. But still, this bug may affect people with other similar layouts too.

STEPS TO REPRODUCE
1. Choose Estonian (US) layout in the Settings → Keyboard → Layouts.
2. Try typing RAlt+U, expecting a "ü" to be entered.
3. Observe "₴" instead.

Comment 1 Ilya Zverev 2024-02-13 08:42:50 UTC
One thing I forgot to test: when I disable "enable additional typographic symbols" ("misc:typo" in kxkbrc Options), estonian letters show up fine. So the issue is that typographic symbols override letters from the layout.
