I found that in game, after I save litematic using chinese input keyboard, The hotkey M will not response,even if I switch back to english input keyboard. AND when I focus on another window not minecraft (eg edge or notpad),then back to minecraft, hotkey will work fine.

Also minihud has the same issue (minihud-fabric-1.16.5-0.19.0-dev.20210917.191825 tested).

• Minecraft version : 1.16.5 and 1.18.2
• Mod version and malilib version : litematica-fabric-1.18.2-0.11.2 and litematica-fabric-1.16.5-0.0.0-dev.20210917.192300

save my litematic using chinese keyboard. maybe chinese is multi-byte characters.

I assume this is basically the same issue as #110? Try the keybindDebugging option described there to see if that's the case.

#110 yes, can you merge this two issue,I will watch on #110 .
