This does look annoying :-( PR gratefully solicited...

The application pickconfig.tcl supports UTF-8, it does this by reading in the localesetting. The problem is that you set the locale to C which limits its ability to correctly display and manage all characters. You can't expect it to display UTF-8 characters if you tell it to display a different character set.

Is there a workaround ?

Interestingly Unicode support is one of the few new things in the new version of Tcl. (And a new version of Tcl is a rare event: https://www.theregister.com/2024/10/02/tcltk_version_9/?utm_medium=share&utm_content=article&utm_source=linkedin )

The workaround is to use a real locale, rather than the basic "C" locale, which only supports 8-bit standard ASCII. I don't know if there is any way to work around this inside the LinuxCNC code.
