New issue 832 by v.villenave: Wrong UTF-8 encoded filenames passed to gs
http://code.google.com/p/lilypond/issues/detail?id=832

Although Ghostscript is able to handle special characters in filenames,
LilyPond messes up the proper UTF-8 encoding of the external utility calls.

For instance, if your .ly file is named ĉacâ.ly, the PostScript file is
generated but PDF conversion doesn't happen, nor any other conversion:

Calling "lilypond --png ĉacâ.ly"
prints an error message:
  Error: /undefinedfilename in (\304\\x89ac\303\242.ps)

As you can see, the high-byte character is written as \x89ac, however, the
backslash is escaped, which of course makes it an invalid UTF-8 character
considering the \304 before...

(Reproduced with 2.12.2 and 2.13.3, and investigated by Reinhold)
