# How to typeset the German letter ß in \address with amsart

I would like to typeset an author's address which contains the German letter ß, but \ss keeps typesetting as "ss".

Here is a MWE:

% !TEX encoding = UTF-8 Unicode
\documentclass{amsart}

\begin{document}
\title{Title}

\author{Author}

\maketitle

Main text containing the German letter \ss.
\end{document}

It typesets as:

• ss is the right output in small caps. – Ulrike Fischer Aug 4 '20 at 9:15
• One option is to use \textup{\ss}. – Урош Aug 4 '20 at 9:49
