Incorrect keyboard input when using "AltGr" key.

[willemavjc]

• VSCode Version: 1.39.1
• OS Version: Microsoft Windows (Pro) Version 1903 (OS Build 10.18362.418)
• PowerShell Version: 5.1

Steps to Reproduce:

1. Open VSCode
2. Open a Terminal
3. Make keyboard keys input combination of "AltGr + 2 then Space" or "AltGr + 7 then Space"
4. You get the standard key (unexpected) plus the AltGr key (expected)

This happens on an AZERTY keyboard (a Surface Type Cover). I am not able to confirm if this happens on QWERTY too.

On AZERTY keyboards, the keys "2" and "7" consist in 3 characters:

• Keyboard key "2": é (standard) + 2 (shift) + ~ (AltGr+Space)
• Keyboard key "7": è (standard) + 7 (shift) + ` (AltGr+Space)

Note: This dysfunction only affects PowerShell through VSCode. Code workspace is not affected. And native PowerShell also behaves perfectly.

These keys are quite intensively used. Any solution would be appreciated.

Does this issue occur when all extensions are disabled?: Yes

What language/locale are you using?

[willemavjc]

From Windows Settings / Time & Language / Language:

• Windows display language : English (United States)
• Preferred languages : English (United States)

In Preferred languages sub-menu :

• Keyboards : French / AZERTY

Is that what you were looking for?

By the way, I was able to observe the same issue on others computers of the company (with VSCode 1.38.1) with the following settings:

From Windows Settings / Time & Language / Language:

• Windows display language : France
• Preferred languages : French

In Preferred languages sub-menu :

• Keyboards : French / AZERTY

Note: Either git-bash via VSCode or powershell via VSCode suffer the same thing (and only occur via VSCode)

Ok I reproduced the problem. Expected:

• 2: é
• 7: è
• altgr+2: (nothing)
• altgr+7: (nothing)
• altgr+2, space: ~
• altgr+7, space: `

Actual:

• 2: é
• 7: è
• altgr+2: é
• altgr+7: è
• altgr+2, space: é~
• altgr+7, space: è`
