[NTG-context] Bug in supp-pdf.tex/supp-mis.tex (?)

[Andreas Fieger]

Hello,

though this is only partly a context question, I think this is the
best place to ask. I am creating MetaPost figures containing text.
When these are included in a TeX document processed by pdfLaTeX,
context's supp-pdf.tex is loaded to perform the conversion.

Consider the simple MP file (the space is essential)
-------------------------------------- 
defaultfont:="ptmr8r";
beginfig(1);
  label(" 11", origin);
endfig;
-------------------------------------- 

This will result in a file like
%%Page: 1 1
-6.25003 -3.38997 moveto
( 11) ptmr8r 10.00005 fshow
showpage
%%EOF

If this MP file is included in a context document, 
everything is fine. 
-------------------------------------- 
\starttext
\placefigure[][]{}{\externalfigure[minimal.mps]}
\stoptext
-------------------------------------- 

If it is included in a LaTeX document 
-------------------------------------- 
\documentclass{article}
\usepackage[dvips]{graphicx}
\begin{document}
\includegraphics{minimal.mps}
\end{document}
-------------------------------------- 
converted to ps with dvips, still everything 
is fine.

When using
-------------------------------------- 
\usepackage[pdftex]{graphicx}
-------------------------------------- 
and pdfLaTeX to compile the file (this is 
when supp-pdf.tex is used), the " 11" disappears.

I found this problem with every number from 11, 22,
to 99 with a leading space -- even in the middle of
a string: "Text: 118" would come out as "Text: 8".

I don't have any clue what's going wrong.
Any ideas?

PS: Hans was so kind to provide a new supp-pdf.tex 
  after a similar problem with labels
  startimg with an umlaut?

  file=supp-pdf.tex  version=2001.07.27
  file=supp-mis.tex  version=1997.01.04
  are used.


Thanks,
Andreas

search in supp-pdf for you name, and patch:

            \def\dodo##1% Andreas Fieger's bug: (\304...)
              {\edef\!!stringa{##1}% and another one: ( 11) -> \ifx 11
               \ifx\!!stringa\MPspacechar\MPspacechar\else\expandafter##1\fi}%

please test this with previous files as well
