so i was thinking more about this and realized this doesnt happen on my work computer (where i normally use emoji in my git commits.)

this is info for a working version:

maybe my version of windows it the issue.

The Windows Emoji panel doesn't seem to insert emojis correctly into PS 7. Not sure where the problem lies. If you execute the following does it display 🔥 correctly?

"`u{1f525}"

"`u{1f525}" does properly display for me.

It seems to be that pasting into PS with emojis doesn't work right. If you copy to the clipboard the emoji that you just displayed using the Unicode escape string and then try to paste it back into PowerShell - it doesn't work. BTW, you can remove PSReadLine from this situation by running pwsh -noninteractive -noprofile and this issue reproduces. So someone should probably move this issue to the PowerShell repo. Even then, this may be a conhost issue. Yup, just fired up CMD.exe in it's one console window and this reproduces there. Looking more like a Windows/conhost.exe issue and not a PSRL/PowerShell issue. OK, see this issue in the WindowsTerminal repo (also repo for conhost) - microsoft/terminal#1503

@rkeithhill Thanks for referencing the WT issue!
@0xW1sKy emojis are not well supported in PSReadLine today. Here are the related issue: #1329, #949
I will close this issue as a duplicate.
