Bug#760751: [okular] Okular shows "[Please insert PrerenderUnicode{??} into preamble]" in the title bar, when the title of the document contains an umlaut
Hi Thomas,

This is a problem with the specific PDF that you have linked to and not with
okular. What you see in the title bar there is quite literally what is set
as the title for that PDF in the document metadata:
$ pdfinfo einf_dab.pdf
[...]
Keywords: Datenbanken, Einf[Please insert PrerenderUnicode{ü} into
preamble]hrung, Motivation
The producer of this pdf (pdfeTeX-1.21a by the looks of it) needs to be
configured to correctly handle non-ASCII characters in the PDF metadata. If
you had the latex source available, you'd be able to fix this by
regenerating the PDF... The solution is to either tell pdflatex that the
input file is encoded in UTF-8 (for example \usepackage[utf8]{inputenc}) or
to help pdflatex understand how to deal with this character (add
\PrerenderUnicode{ü} to the preamble.)
cheers
