Ghostscript bug when converting PostScript output to PDF.  The
PostScript reads (pasted from less' display)

mark /Creator (LilyPond 2.21.0)
/Title (<FE><FF>^A^M)
/DOCINFO pdfmark

which is the correct UTF16-LE string with BOM.  GhostScript however
converts the ^M (0x0d) into ^J (0x0a), basically converting an ASCII CR
to an ASCII LF.  Unfortunately, we are not in the middle of ASCII here.
