I've just installed version 6.11.11.
If I try to type a closing brace '}', nothing happens. As far I have tried so far, no other characters have been impacted.
Please note that I use the Italian keyboard layout, where the keystrokes to accomplish '}' are Ctrl + Alt + Shift + ']' (in terms of US keyboard layout) or AltGr + Shift + ']'.
If I switch to the US keyboard layout, everything works.
Could this be related to a newly-added keyboard shortcut, together with the non-US keyboard layout?
