I use relsize to create a pretty version of the string "C++". This produces warnings when put into footnotes or small environments, because the result would be "too small". How can I prevent this without having to resort to a different macro for those situations?
This is a MWE:
\documentclass{scrbook}\usepackage{xspace}\usepackage{relsize}\usepackage{hyperref}\def\cpp{\texorpdfstring{\protect C\nobreak\hspace{-.05em}\raisebox{.4ex}{\relsize{-3}\textbf{++}\xspace}}{C++}}\usepackage{scrhack}\begin{document}\chapter{one}\cpp\ worksfoobar\footnote{\cpp\ produces warning}\chapter{two \cpp}\end{document}The warning produced is:
Package relsize Warning: Font size 5.20834pt is too small.(relsize) Using 6.0pt instead on input line 18.I have tried using \scalebox{.5}{\textbf{++}} instead of relsize. This works nicely for the footnote, but then the command cannot be used as part of a chapter-title anymore.
