Some characters that use modifiers are not printed

[elferherrera]

Using a spanish keyboard layout, in order to access to the chars [ ] or { } one needs to use the modifier alt gr. Reedline does not print those characters when using this layout. If I change it to an english layout, the characters can be printed (they dont need the alt gr key).

This is the output from cargo run -- -k

It seems that the events are captured, but reedline doesnt print the characters

With your fix in #139 this seems to be resolved. I was able to enter AltGr characters with a German keyboard layout in two terminal emulators (gnome-terminal, vscode)
