Original Pull Request: https://github.com/microsoft/terminal/pull/8870

State: closed
Merged: Yes

Pressing Ctrl+\ produces ^\ using the US keyboard layout, thanks to Ctrl-key mappings inside the keyboard layout, whereas some layouts, like the UK extended layout, don't contain those. This causes the character value to be zero and previously caused no VT sequence to be generated under these situations. This PR employs MapVirtualKeyW to infer the missing characters.
As a side effect this PR effectively causes all major keys on the keyboard to produce Ctrl+combinations now.

PR Checklist

Validation Steps Performed

Compared all major keys in combination with Ctrl with the app store version of Terminal using showkey in WSL. All keys that previously worked still appear to continue to work.
