Really, you are simply missing the point, which is

because you cannot pass Unicode strings.  That is all.

The ISO 8859-1, also known as Latin-1 character set is simply a superset of
ASCII, that is ASCII specifies characters 0 to 127 and Latin-1 specifies
characters 0 to 255 with characters with the code 0 to 127 being identical
to ASCII.  It provides many characters used in European languages.

Further, Unicode supports all ISO 8859-1 characters with exactly the same
encoding plus another million or so characters.  UTF-8, as support by
POV-Ray is just a transfer encoding of Unicode characters with a few special
properties, one being that characters 0 to 127 are identical to ASCII.

Windows, like by far most operating systems you will find today, initially
did not support Unicode simply because Unicode was only defined in 1991.
Instead, systems use other tricks that essentially assign the codes 128 to
255 (more does not fit into a single bytes) different characters depending
on the language the operating system is set to use.

However, this all has absolutely nothing to do with POV-Ray not being able
to support Unicode filenames.  The fact that you can enter them somewhere in
some operating system says absolutely nothing.  Explaining this in the level
of detail and with all the background for you to understand it is simply not
possible in a news message.  So, I suggest you just accept the fact that
what you are looking for isn't possible to do in a portable manner for the
time being.  This may change in a few years, but has absolutely nothing to
do with POV-Ray.
