I need to write Heß in all caps. My publisher does not want XeTeX, so I have to find a good way to get the uppercase ß. The simplest way would be to just use the lower case ß instead. Based on this I tried that:
\documentclass{article}
\begin{document}
\newcommand\newss{\MakeLowercase{ß}}
\MakeUppercase{He\protect\newss}
\end{document}
.. to no avail.
I cannot redefine \MakeUppercase. Any suggestions on how to proceed?
