Update of bug #53922 (project octave):

Follow-up Comment #15:

The "*env" functions also lack support for non-ASCII characters on Windows.
Among other things, this leads to problems for users with non-ASCII user
name.
Gnulib doesn't support the Windows Unicode API either. So we have to write our
own wrappers anyway if we want to enable users with non-ASCII scripts to use
Octave natively.

The attached patch switches to use the Windows Unicode API for setting,
querying and un-setting environment variables. All of these are
case-insensitive.

There was a bunch of FIXME notes that I just carried over. I don't know
whether they all still apply. Particularly this one in lo-sysdep.cc (after the
patch):

FIXME: make this do the right thing if we don't have a SMART_PUTENV.


Was this referring to the problems with Windows (only)?
