I noticed that setting the code page is not enough to support Unicode in the Command Prompt and PowerShell applications. Certain characters show up, but many emojis show up as question marks instead.

This does work (mostly) when using the new Windows Terminal.

I've noticed another issue that may be related.

The output of this code has some issues, even in Windows terminal:

import WinSDK
_ = SetConsoleOutputCP(UINT(CP_UTF8))
print("�‍♂️��‍���������")

The male face palm emoji shows up as a female face palm emoji, followed by a male gender sign. The other emojis are seemingly followed by other (invisible) characters as well, as there are spaces in the output.

Basic emojis work fine.

[EDIT: The emojis in my example displayed when I posted this, but now there seems to be an encoding issue here as well, as I'm posting this from Windows. To reproduce this issue, you can use the male face palm emoji]

Will this be in 5.5.3?

This hasn't been backported to 5.5.3. I suppose that it is a nice enough improvement, windows specific and pretty self-contained. I'll see if I can backport it.

This is fixed on main. Backporting to 5.5.3, while interesting, is not tracked by this issue.
