Environment

Windows build number: 1903 18362.267
Windows Terminal version (if applicable):  0.3.2142.0

Steps to reproduce

Window Terminal have to be possible to use internationally.
"international localization" is the keyword which have to remember.

Cant give chars @ $ £ { [ ] } because keymapping ctrl+alt+1-9 kill those keys ex. in swedish, finnish, ... keyboards.

• @ = AltGr+2
• $ = AltGr+4
• ...

Expected behavior

After I changed those tabbing keymapping ex. ctrl+shift+1, ctrl+shift+2, ... I got those important shell level characters from my keyboard as they have been since 199x.

Actual behavior

Issue #521 has been same problem, but it looks that this is not same, low level problem has fixed.

Problem is same: AltGr not work. Current problem is easier to fix: Don't kill AltGr in default configuration using ctrl+alt+N (N=1-9) key mapping.
