kdeconnect-kde-mirror/plugins/mousepad/waylandremoteinput.cpp
Lyra Rebane 0d2caec23c [plugins/mousepad] Allow uppercase keysyms for portal input 
Currently all keyboard input is converted to lowercase. Combined with the shift key this can still produce an uppercase key, but that doesn't seem to happen for everyone.

See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1111516
