Pasting a single certain Unicode character results in two garbage characters being pasted instead

[snaar]

Windows Terminal version (or Windows build number)

10.0.18363.1440, 1.7.1033.0

Other Software

N/A

Steps to reproduce

1. Copy some "high" unicode character into buffer, for example U+1FB37 '🬷'. You can also copy it from https://www.fileformat.info/info/unicode/char/1fb37/browsertest.htm
2. Paste it into terminal.
3. Optionally paste it into notepad for comparison.

Expected Behavior

Expected actual character. Or if font doesn't support it - single box character.

Actual Behavior

After pasting terminal shows two box characters:

If you paste same thing into notepad it shows up correctly:

Incidentally, if you paste it into old cmd.exe, it shows up as box, but still only a single box:

It's possible it's related to #9308

I think this is actually more broadly #190 and #1472. cmd.exe and Windows Powershell are notoriously bad at handling unicode characters.

Er, after reading more carefully, this might even be #9052

That's really annoying when pasting file/folder paths copied from File Explorer.

Every day I face paths like:

C:\Users\<REDACTED>\<REDACTED>\Innovation Labs – Projects - Documents

and I can't paste them into PowerShell commands running within Windows Terminal.

Is this still an issue? If my theory was right that this was #9052, that was fixed in 66b9b9d which shipped in v1.9.1445.0, back in late May 2021.

[snaar]

Still reproduceable in 1.11.3471.0.

Actually it looks like there is regression in cmd.exe now too - it shows two box characters now instead of one like it used too:

Okay then this is probably just /dup #1503 which covers the much broader issue here. "emoji" is being used as a synonym for "anything that isn't just a single WCHAR". Thanks for following up!
