Some key combinations that use AltGr on French keyboards do not work

[sba923]

Issue Description

I'm running the 2.0.1 preview with PSReadLine 2.0.0 beta 4 and am experiencing the following:

• AltGr+2 (dead key) followed by SPACE yields é~ instead of ~ (the é is displayed immediately, before I hit SPACE)
• AltGr+7 (dead key) followed by SPACE yields é` instead of ` (the è is displayed immediately, before I hit SPACE)

Workaround: Use Ctrl+Alt+2 / Ctrl+Alt+7

(I've also reported this here)

Expected Behaviour

• AltGr+2 followed by SPACE should yield ~
• AltGr+7 followed by SPACE should yield `

Actual Behaviour

• AltGr+2 followed by SPACE yields é~
• AltGr+7 followed by SPACE yields è`

Attached Logs

(can't gather logs at this point -- all I get is "command 'PowerShell.OpenLogFolder' not found)

If this is occurring the the PowerShell console host as well (with the same behaviour), it's probably best to track this in PSReadLine -- the fix will come from there

[sba923]

Yes it does also occur in the PowerShell console host, so it's definitely a PSRL issue that needs to be tracked there.

In the meantime, it does impair the VScode/PS experience, so the extension can't leave preview status until this is fixed if you ask me.

Oh BTW, the Ctrl+Alt workaround seems to work reliably in VScode, but not in the PowerShell console host, for some reason.

Closing this as this is a PSRL issue, and should be tracked there...also tracking the preview status of PSRL not being ready to leave preview status here #1793 thanks!
