[O] Diacritics in image file names

[François Pinard]

Hi, Org people.

It seems that if I use diacritics in file names for included images, and
then asks for a PDF rendering of it (through LaTeX), the image does not
get included.  If I remember correctly, I only get a big hollow square,
with the textual name of the image file (rather than the image) included
in the square and extending out to its right.

The file name uses UTF-8, as well as the Org file referring to it.

If I rename the file to pure ASCII, and adjust the reference
accordingly, all goes well.  So did I, of course.  Yet, I think the
problem is worth being reported, and then, either corrected or
documented (so other people do not spend time scratching their head).
