for latex, ppchtex is loaded via ppchtex.noc which says ...

\let\normalunexpanded\unexpanded

\input supp-mis.tex  \let\writestatus\undefined
\input syst-gen.tex
\input syst-fnt.tex

\let\unexpanded\normalunexpanded

(\unexpanded is an etex primitive but context had an \unexpanded before 
etex came around; same for \protected as primitive; so here we push and 
pop the meanings)

so, i wonder if this user loads ppchtex in the right way

(maybe i should make a derived version for latex usage - given that 
there are users - in which case i can also cleanup and optimize the 
context variant, but it has low priotity)
