Ohmmm ... strange that switching to utf8 breaks reading files
which are named with utf8 multi byte characters.  I guess that
now utf8 characters are handled/mapped to the correct font
character glyph.

And indeed \UseRawInputEncoding before \input does help. Does
this mean that I've now hack texi2pdf/texi2dvi as well as AucTex?
Or is it possible that the utf8 based engines also can handle
utf8 characters in file names (utf8x)
