With x11-misc/xkeyboard-config-2.23.1 command: setxkbmap -layout pl -option "eurosign:5,altwin:meta_super,kpdl:dot" return "Error loading new keyboard description" and exits with code 251. After that, Polish diacritic shortucs (right alt + letters like a, c, e, l, n, ...) don't work. With x11-misc/xkeyboard-config-2.22 works as expected.
I can confirm - xkeyboard-config-2.23.1 spoile "pl" layout. Downgrade fixed issue.
Edit: It seems that this is upstream bug, fixed in current master: https://cgit.freedesktop.org/xkeyboard-config/commit/?id=9a5cecf64ffc427a6a5a7c9a061992c32e5b8a4f I didn't try to patch and test it.
