Short description of error
Dead keys not working in wayland but ok in X11.
Exact steps for others to reproduce the error
When running blender with wayland and "US intl dead keys" keyboard layout, the dead keys are dead.
Expected behavior (works when running X11) :
"+ [space] should produce "
'+ [space] should produce '
"+a should produce ä
`+e should produce è
...
What i get in wayland is:
"+[space] produces [space]
'+[space] produces [space]
"+a produces a
`+e produces e
...
I can reproduce this on Arch (KDE) and Tumbleweed (KDE and Gnome).
My current workaround is to run blender X11 in a vm.
Same problem in versions 3.6.1, 3.6.5 RC and 4.0.0 beta .
@ideasman42 , can you check?
@Bertrand-Rubli hi, from what I can see X11 doesn't have explicit support for dead-keys, it may be that the X11 API's provide text from dead-keys were as the Wayland API don't.
Blender supports IME on Wayland, as of:
a38a49b073.From testing with GNOME, it looks as though dead-keys may be implemented using IME. In GNOME's "Keyboard" preferences, with the "Compose Key" set, this key prompts for further input so so [
compose+a+,] results inąfor example.Could you check if this works on your system too?
Tested in vm running Tumbleweed, Gnome 45, Blender 4.1.0 latest.
I configured the compose key and tested it with standard and dead keys layout.
Everything works in gnome console, but unfortunately not in blender (tested in python console).
Sorry :(
Would you be able to test with input fields (object name for e.g.).
The Python console doesn't support IME, but text fields do. If Wayland needs IME for dead-key support we might have to add IME support for other text input in Blender.
Tried with renaming objects and in search field.
Blender ignores the "Compose Key".
But i found that the "Alternate Characters Key" can be used to produce quotes and special characters in text fields and python console.
Committed dead-key support
57a5c6c4befor 4.0 (since this works in X11, it's a regression in functionality not to support this in Wayland too).Supporting this functionality in GNOME was a bit confusing as dead keys use IME when available and fallback to
xkb_compose_*, so there are two ways it can be supported.Blender 4.0 only has dead-key support, 4.1 supports both dead-keys via a compose key & input methods (IME). This is needed for dead-keys to work in the console & text editor since IME is only used for Blender's text UI elements.
