Answer 1

I presume the problem stems from chcp 65001 being in effect, ie the UTF-8 code page.

With code page 65001 in effect, powershell.exe - the CLI of Windows PowerShell - indeed unfortunately exhibits the symptom you describe: the currently selected font is changed to a legacy raster font with limited glyph (character) support.

The following command demonstrates the problem (run from cmd.exe ):

:: Unexpectedly switches to a raster font.
:: Note: No longer occurs in PowerShell (Core) 7+, with pwsh.exe
chcp 65001 & powershell -noprofile -c "'hi'"

---

You have the following options :

• Run your batch file in Windows Terminal , available in the Microsoft Store instead of in a legacy console window.

• You can temporarily switch to a code page other than 65001 , assuming it still supports all the characters you need ; applied to the example above:

   chcp 437 & powershell -noprofile -c "'hi'" & chcp 65001

• You can switch from Windows PowerShell to PowerShell (Core) 7+ , the install-on-demand, cross-platform successor edition. Its CLI , pwsh.exe , no longer exhibits the problem.
