I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

I tried running set DOTNET_CLI_UI_LANGUAGE=ja-JP and chcp 65001 and dotnet --info, in cmd on Windows 10 Version 21H1 (OS Build 19043.1165).

• In conhost, using "Consolas" font:
  Question marks in rectangles appear, but if I copy them to the clipboard and paste to WordPad, then Japanese characters appear in WordPad.
• In Windows Terminal Preview 1.10.1933.0, using "Consolas" font:
  Japanese characters appear.
• In OpenConsole.exe copied from Windows Terminal Preview 1.10.1933.0, using "Consolas" font:
  Japanese characters appear.

I think this is a conhost issue and will be fixed in some later version of Windows when the changes from OpenConsole have been merged in.

@KalleOlaviNiemitalo Thanks for helping to identify the root cause, if I copy the question mark characters to another editor then Japanese characters appear. Or If I change the font of conhost, the Japanese characters also display as normal.
Since this is a conhost issue, I'll close this issue. Thanks.

microsoft/terminal#10478 may have fixed this in OpenConsole. I don't know which version of Windows will include a conhost with this change.
