My document contains section titles that are formatted by the listings package. (The section names are names of configure script switches.)

\subsection{\lstinline!--enable-so-version!}\label{enable-so-version}

I am getting the following warning when processing the LaTeX source:

Package hyperref Warning: Token not allowed in a PDF string (Unicode):
(hyperref)                removing `\lstinline' on input line 231.

Can I avoid it anyhow? I would be willing to duplicate the title string without the listings formatting decoration if there were a directive to set the PDF TOC entry string manually (instead of automatically).

Many commands that works via unexpandable stuff (assignments, catcode changes, ...) do not work in bookmarks. A PDF viewer is not TeX and does not understand the TeX language.

Package hyperref provides \texorpdfstring to provide different code for the normal case and the bookmark case:

\documentclass{article}
\usepackage{listings}
\usepackage{hyperref}
\usepackage{bookmark}

\begin{document}
  \tableofcontents
  \section{%
    \texorpdfstring{\lstinline!--enable-so-version!}%
                   {-{}-enable-so-version}}
\end{document}

Result

Remarks:

  • The curly braces inside -{}-enable prevent that the bookmark code makes a ligature and converts the two single hyphens to an en dash.
  • Package bookmark is recommended, the bookmarks are faster up to date and the package provides more features.
