Check possible clashes with accsupp

[u-fischer]

accsupp adds also BDC/EMC tags, so it must be checked if this clashes.

It looks as if mixing both it okay

\documentclass{article}
\usepackage{accsupp}
\usepackage{tagpdf}
\tagpdfsetup{activate-all,uncompress}
\pagestyle{empty}
\begin{document}
\tagstructbegin{tag=Document}
\tagstructbegin{tag=P}

\tagmcbegin{tag=P}
\BeginAccSupp{method=hex,unicode,ActualText=2226}
blub
\EndAccSupp{}
\tagmcend

\tagstructend
\tagstructend
\end{document}

But there seem to be interferences with automatic /Actualtext from luaotfload
