Thats true. While latin1 can include every possible character, UTF-8
cannot. (possible as possible to have on the wire)

Why converting the filename at all? The file name is the same on command
line and on the file system. So without any reencoding everything would
be fine.

I never had that problems with latin1 (except with only few software
like luatex). But I had many problems in past with trying to use UTF-8.
However, that personal stuff is good to know but does not help in this
situation.

Fact is that even software that uses UTF-8 (or other unicode) internal,
work well in my environment. (Examples: Libreoffice, Gimp, Geeqie, ...
(Geeqie, I am one of the people working on it)) So it must be possible
to do that in lualatex or xetex too.

I did a fast divein to the lualatex code but did not find the current
entrypoint to fix that. There are many indirections around filesystem
code, that I do not know why it is done this way.
