[textcase] Accents in (e.g.) `\MakeTextLowercase` used to work but don't work anymore

[dbitouze]

The following MCE:

\documentclass{article}
\usepackage{textcase}
\begin{document}
\MakeTextLowercase{Café}
\end{document}

used to compile (with pdflatex) like a charm with an up to date TL 2021 but, with an up to date TL 2022, that's not the case anymore:

! LaTeX Error: Invalid UTF-8 byte sequence (��\ifx).

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...                                              
                                                  
l.24 \MakeTextLowercase{Café}

You did not show your log but hopefully that error was not using the version from this repository, I get no error on your test and a log

Package: textcase 2022/06/12 v1.02 Text only upper/lower case changing (DPC)

that version went to ctan yesterday so should be in texlive today or tomorrow, see also

OK. As advised, I rely now on \MakeLowercase instead of \MakeTextLowercase.
