Non-English character input in normal mode

[minty99]

As a Korean user, I have encountered an issue with the normal mode in this extension.
When I type Korean characters, they are directly inserted even in the normal mode (not on insert mode).

Is there a workaround or a setting that could either ignore these Korean character inputs or smartly convert them to English characters in the normal mode? I believe simply ignoring the key input for Korean (or other languages except English) characters in the normal mode would be a sufficient solution.

I'm having the same issue using brazilian portuguese layout. Is there a way to associate keys with "keyCode" instead of "code" or something like this?
