\newcommand{\SETUPDOC}{%
This test uses Babel's built-in Greek support (``ini'' file,
cf. \href{
https://latex3.github.io/babel/guides/locale-greek.html}
{Babel>Locales>Greek}).
The following problems can be easily fixed by loading the \emph{textalpha}
package.
\begin{itemize}
\item Accents not dropped with old (pre 2022/06) \cs{MakeUppercase}.
\item Greek LICR macros unknown in TU.
\end{itemize}
The new 2023/02/10 \cs{MakeUppercase} code fixes the UPPERCASE of Greek
Unicode literals (including a fix for the ``hiatus'' problem).
