[Markus Mützel]

Update of bug #63400 (project octave):

                  Status:                    None => Patch Submitted

Follow-up Comment #7:

I tried to better understand what the readline patches are actually doing. In
particular, the patch "readline-2-event-hook.patch".

I believe I got it to a point where the arrow keys are working again in the
CLI (and the GUI). Also, it is now possible to enter non-ASCII characters in
the command window. And random non-ASCII characters no longer lead to crashes
of the console host for me. 🎉

I don't know if any of those changes depend on a certain Windows version. The
used functions (`ReadConsoleInputW` and `WideCharToMultiByte`) should be
available in Windows 2000 and newer. I don't know if the characteristics of
the console changed at some point though. I am on Windows 11 if that should be
important.

I'm attaching a patch with the changes for MXE Octave. I'd appreciate if
someone could test them. (Maybe on other Windows versions?)
Also, any proof-reading would be much appreciated.
