Terminal: Incorrect pasting when copying some uppercase Cyrillic characters

[farag2]

Environment

Windows build number: 10.0.19041.0
Windows Terminal version (if applicable): 1.1.2233.0

Steps to reproduce

Some (not all) uppercase Cyrillic characters e.g. "А", "Б", "В" couldn't be pasted or typed in Windows Terminal. Also "Ы", "Я" could be pasted/typed.
I've discovered it when tried to paste

Start-Process -FilePath "$env:ProgramFiles\Mozilla Firefox\firefox.exe" -ArgumentList "-new-tab https://ru.wikipedia.org/wiki/Свободное_программное_обеспечение#Введение_ограничений_для_ПО"

Expected behavior

The string above should be pasted.

Actual behavior

Start-Process -FilePath "$env:ProgramFiles\Mozilla Firefox\firefox.exe" -ArgumentList "-new-tab https://ru.wikipedia.org/wiki/Свободное_программное_обеспечение#ведение_ограничений_для_"

As you can see Введение_ограничений_для_ПО became ведение_ограничений_для_ by cutting all uppercase characters.

May be related to https://github.com/PowerShell/PSReadLine/issues/1603 and hence https://github.com/dotnet/runtime/issues/38966. Try workarounds:

• Remove-Module PSReadLine
• or remove the Ctrl+V binding from settings.json of Windows Terminal and then use Ctrl+V to paste (rather than Ctrl+Shift+V or right mouse button)

Thanks. Fixed after installing latest stable PSReadLine.

Out of curiosity, which version of PSReadLine did you have before? I was not able to reproduce the issue with PSReadLine 2.0.2 installed as part of PowerShell 7.1.0-preview.5, even when using a Russian keyboard layout.

A default one: 2.0.0 (PS 5.1). The version distributed by default on Win 10 2004. Then I tested on VM with fresh installed 2004 and faced the same bug.

Thanks for the info! Yeah, the built-in version of PSRL is a little bit outdated (it is 2.0.0-beta3, if i recall correctly?).

Looks like this one is external/fixed for you :smile:
