hyperrefsectioning
In my thesis, I have math/Greek expressions in some of my section headings.
I am given the error message:
Token not allowed in PDF string. I found \textorpdfstring{} from similar questions posted, and although it works in the final PDF, I would prefer to not have the error.
\subsection{\textorpdfstring{$E1$} transitions in and out of the
\textorpdfstring{$\kappa$} band}
Thanks!
The simplest thing is to patch \@startsection and \@chapter (assuming book or report class):
\usepackage{etoolbox}
\makeatletter
% \tracingpatches
\patchcmd{\@sect}{#8}{\boldmath #8}{}{}
\let\ori@chapter\@chapter
\def\@chapter[#1]#2{\ori@chapter[\boldmath#1]{\boldmath#2}}
\makeatother
#8 is the argument to \@sect that contains the title; but \boldmath will not leak to the table of contents nor to the headers (for headers it's sufficient to use fancyhdr and issue \boldmath, if bold headers are desired).
It doesn't work with \paragraph and \subparagraph, nor with \chapter*. It shouldn't be a problem to issue \boldmath in the argument of an occasional \chapter*.
You can profit of my usebib package:
\documentclass{article}
\usepackage[backend=biber]{biblatex}
\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@ARTWORK{gizapyramid,
title = {Pyramids at Gizeh},
year = {ca.\@ 2500 BCE}
}
\end{filecontents}
\addbibresource{\jobname.bib}
\usepackage[hidelinks]{hyperref}
\usepackage{usebib}
\bibinput{\jobname}
\begin{document}
\section{\texorpdfstring%
{\citetitle{gizapyramid} (\citedate{gizapyramid})}%
{\usebibentry{gizapyramid}{title}}}
\end{document}

I think two separate issues need to be addressed:
The command in question is called
\texorpdfstring, not\textorpdfstring.The command takes two arguments -- the TeX string (which can contain math tokens) and the pdf string, which should not.
The following code runs fine. Incidentally, the
\boldmathinstruction at the start of the argument of\sectionis optional.
