I tried all the vnc-clients I could find (real, tight, tiger, turbo), tried different keyboards and changing system keymaps of libreelec and ui language/keymaps but nothing helped. Copy, paste seems broken, nothing is being pasted.
I connect from Win 10 pro with de_DE keymap set on the local machine. Currently using real VNC-Viewer.
LibreELEC Version: devel-20181130210330-#1130
Currently LibreELEC is setup like so:
Interface language: english
Character set: default
Keyboard layouts: German QWERTZ
Region default format: Central Europe
LibreELEC keyboard Layout: de-latin1-nodeadkeys
locale(set through official locale addon): de_DE
Some of the chars I get when connected with any vnc client:
SHIFT+"='Ä'
SHIFT+#='Ä'
#=3
SHIFT+6=/
ALTGR+ß=#
SHIFT+:=Ö
