[Octave-bug-tracker] [bug #59572] "system" doesn't work with non-ASCII characters on Windows

[Markus Mützel]

Update of bug #59572 (project octave):

                 Summary: "system" doesn't work for non-ASCII characters on
Windows => "system" doesn't work with non-ASCII characters on Windows

    _______________________________________________________

Follow-up Comment #2:

Attached is another (independent) patch for non-ASCII characters in commands
in asynchronous mode on Windows.

I still don't know how to fix the synchronous mode with output.
The commands themselves seem to be executed using a pipe. That already works
with non-ASCII characters. But if the output contains non-ASCII characters, it
is broken currently.

The key is probably to understand how `iprocstream` works in
`run_command_and_return_output` here:
https://hg.savannah.gnu.org/hgweb/octave/file/54509b7fddd3/libinterp/corefcn/toplev.cc#l104

Can it just inherit from `std::wios` instead of `std::ios` and everything will
fall in place correctly? If that is the way to go, that would probably mean a
lot of duplicated classes.
Is there a better way to implement this?
