Description

When pressing the key sequences AltGr-f, AltGr-c, AltGr-m, etc. (for [, & and < characters, respectively), the cursor blinks but nothing happens, the requested characters are not typed in.

Environment

• Contour Version or Git commit hash: v0.1.0_prerelease_120 c2add12
• Operating System (name / distribution / version): Windows 10 x64 1909
• Contour configuration: default (? I think... I did not change anything.)
• TERM environment variable: xterm-256color
• Compiler version: N/A (Installed from release)
• Keyboard layout: huHU

By default, the terminal starts PowerShell. The modifier characters work in the standard PowerShell window. I'm ssh over to a Linux machine, but it doesn't help the case. (Normal Git Bash MINTTY works properly.)

Steps to Reproduce

1. Download release version for Windows, and unpack it.
2. Start bin/Contour.exe
3. Try to type in & by pressing AltGr-c, observe nothing happens.
