I have been using the microtype package together with the fontsetup package. The document seems to compile normally. Protrusion and expansion also seem to be working, but I usually get around 100 warnings from microtype.

I would just ignore the warnings, but it is really annoying if you are trying to debug a compile error and the actual mistakes gets lost in the multitude of errors and warnings.

What do these warnings actually mean? Is there a way to disable the warnings? (Sorry, I am not too versed in microtype).

I would really appreciate a answer, as it would make it easier for debugging erroneous code.

MWE:

\documentclass{scrartcl}
\usepackage{polyglossia}
\setmainlanguage{german}
\usepackage[default]{fontsetup}
\usepackage{microtype}
\usepackage[math]{blindtext}

\begin{document}
    \blindtext[4]
\end{document}

I tried using the Hints and Caveats provided in manual, but maybe I did sth wrong there. I tried

\DeclareMicrotypeAlias{NewCMRoman}{LatinModernRoman}
\DeclareMicrotypeAlias{NCM-default}{TU-basic}
\DeclareMicrotypeAlias{NewCM10-Book}{TU-basic}
\DeclareMicrotypeAlias{NCM-TU}{TU-empty}

    This is a glitch in luaotfload, which currently doesn't recognise all slot names. It has been fixed in the development version. Until the next luaotfload release, you could suppress the warnings with \usepackage[verbose=silent]{microtype}.

  • @Robert Ok thx. So I either get the development version off of GitHub or wait for the release and use [verbose=silent] for microtype at the moment, right? Commented Jan 21, 2022 at 16:04

    that's right...
