Emoji input doesn't input anything

[mbartlett21]

Environment

Windows build number: Microsoft Windows [Version 10.0.18363.815]
Windows Terminal version (if applicable): 

Any other software?

This is using Lua, edited to execute chcp 65001 > nul before reading any input.

Steps to reproduce

When entering a line into Lua, enter a unicode emoji.

Expected behavior

The emoji would be read as four utf-8 bytes: \xf0\x9f\x99\x82

Actual behavior

The line is only read up to the emoji (not including it).

Notes

When I tried this in cmd (also through MS Terminal), it entered correctly, resulting in
'😀' is not recognized as an internal or external command, operable program or batch file.

Lua uses fgets to read a line.

I tested _getch as another method and it had the same problem (It refused to read anything unless it was ASCII and not an emoji).

Or, rather, a C program whose fgets() devolves onto ReadFile() does not read characters greater than U+00007F … which is issue #4551 .

Ok. I'll close this then.
