Hi,

I'm new to both luatex and this list and I hope my question is in the
scope of this list:

I tried to wrap this in a \startlua -- \endlua pair, but this fails:

\def\startlua{\directlua0\expandafter\bgroup\detokenize\bgroup}
\def\endlua{\egroup\egroup}

\startlua
tex.print("\\uppercase{Hallo Welt}")
\endlua

If I replace the "\endlua" with "}}", it works.  I even messed around with
\catdoc\}=12 and things like that, but didn't succeed.

TIA,
olli

Sorry that this mail misses the references-header, but the webinterface
doesn't show the mids.
