Change font in caption/headings text

[lulabelle]

Hi,

I have a document where I use a specific definition to put a specific word always in
another font: i.e.:

\usepackage[T1]{fontenc}
\def\bubu{{\renewcommand{\rmdefault}{pfu}\textrm{bubu}}}

I then use \bubu in the body text to get the word bubu in the preferred font.
This works fine, but it doesn't work in headings and captions. I didn't found
any hints on the web how to resolve this problem without changing the font of the whole
caption/heading. To be clear, I want to have something like this:

\begin{figure}
\caption{Normal text, normal text, \bubu in other font, normal font again}
\end{figure}

Many thanks in advance for any hints regarding the problem.

Use \DeclareRobustCommand\bubu instead of \def\bubu.

As an alternative, you could use \protect\bubu instead of \bubu where no fragile commands are allowed, i.e. inside captions and headings.

a bit shorter:

Code: Select all  •  Open in writeLaTeX

\protected\def\bubu{{\fontfamily{pfu}\selectfont bubu}\xspace}

The \xspace from the xspace package allows you to write A \bubu B instead of A \bubu\ B.

Many thanks it works fine! But if I use the new command in a section or subsection title
the text is printed in the default font. In the table of contents however the font of
the subsection titles are printed in the correct font, but in the real document the default
font is used. The font of the section title however are also printed in the default font in
the toc.

Could you please provide an MWE? I tested this code (using Times) and it worked everywhere:

Code: Select all  •  Open in writeLaTeX

\documentclass{article}

\usepackage{lmodern}
\usepackage[T1]{fontenc}
\usepackage{xspace}

\protected\def\bubu{{\fontfamily{ptm}\selectfont bubu}\xspace}


\begin{document}

\tableofcontents
\listoffigures

\section{Normal text, normal text, \bubu in other font, normal font again}

\begin{figure}
\caption{Normal text, normal text, \bubu in other font, normal font again}
\end{figure}

\end{document}

Oh, I found my error. Your test file totally works fine.
I had a faulty bold version of my used font. Sorry for the inconvenience
and many thanks for the fast help ...
