# How to make \textregistered or \texttrademark bold in subsection title?

\documentclass[]{scrreprt}
\DeclareTOCStyleEntry[numwidth=3em]{tocline}{figure}
\DeclareOldFontCommand{\bf}{\normalfont\bfseries}{\mathbf}
\usepackage[outline]{contour}

When I define a new subsubsection with a trademark or textregistered symbol, the output of this symbol is not bold. Using \usepackage[outline]{contour} makes the symbols bold in the text but not in the subsection title. Is there any way to bold these symbols in the title?

Edit: deleting the ae package and replacing it with lmodern resolved my problem.

• I get a bold trademark in a minimal example (without needing contour). So show a complete example. Oct 27, 2020 at 12:19
• @UlrikeFischer what do you mean by complete example? Oct 27, 2020 at 13:31
• Usually, the idea when giving examples on this site is to make them minimal, yet compilable so that others can reproduce your problem easily. More details are given in the answers on this meta question. Oct 27, 2020 at 15:22
• Remove \usepackage{ae}. It's obsolete and deprecated. Oct 27, 2020 at 17:28
