[Tex/LaTex] How to make \citetitle work in a hyperref section bookmark

biblatexbookmarkshyperref

I'm trying to use hyperref on a very large number of section headings for pieces of artwork in a document, but I have to use a workaround to get the title of the artwork into a bookmark of the section:

\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}

\begin{document}

\section{\texorpdfstring%
{\citetitle{gizapyramid} (\citedate{gizapyramid})}%
{Pyramids at Gizeh}}

\end{document}

Doing that properly displays "Pyramids at Gizeh" in the bookmark; however, since I occasionally find myself tweaking the title of various artworks to more accurately match common names, I would like to do something like this:

\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}

\begin{document}

\section{\texorpdfstring%
{\citetitle{gizapyramid} (\citedate{gizapyramid})}%
{\citetitle{gizapyramid}}}

\end{document}

The problem with that is it throws the warning:

Package hyperref Warning: Token not allowed in a PDF string
(PDFDocEncoding): (hyperref) removing `\citetitle' on input line 20.

Then, it displays the tag "gizapyramid" in the bookmark instead of "Pyramids at Gizeh" as desired.

How can I make \citetitle work in a hyperref section bookmark like I want without ruining its normal behavior elsewhere in the document?

Best Answer

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}
