Shelling out to `mode` on Windows can fail due to encoding issues

I was not aware of that, thanks. I think its from Proc itself and the NORMALIZE_ENCODING:
https://github.com/rakudo/rakudo/blob/nom/src/core/Proc.pm#L43
I imagine most things that use Proc and read from .out will encounter the same error right now unless the encoding is manually set

I have an idea to workaround it using unpack to decode instead, but could you paste the German output of mode so I can test the regex?

Sure. Here's what I get on a pristine cmd terminal:

Status von Gerät CON:
---------------------
    Zeilen:          300
    Spalten:         80

# error?
perl6 -e ".say for shell('mode', :out).out.lines"

# ok?
perl6 -e ".say for shell('mode', :out, :enc('latin-1')).out.lines"

I suspect this could fix this specific instance. There are others that will need to be looked at now, but the stdout from those usually is printed back out to the terminal so may require a more targeted solution.
