Hi Peter, Friedrich, and others,

    What a great thread this has turned out to be.

Here are some tips from my own explorations, guided by these ideas.


This works fine for me:

%% filename hällö.tex
%%
\documentclass{ltxdoc}
\usepackage{xspace}
\usepackage[latin1]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{palatino}
\begingroup
\let\\\relax
\immediate\write18{%
   pwd | iconv -f UTF-8-MAC -t ISO-8859-1 |
     awk -F'\\n' '{print "\\gdef\\directorypath{" $1 "\\xspace}"}' >  
tmpdatei.tex
   }
\immediate\write18{%
   echo "\jobname" | iconv -f UTF-8-MAC -t ISO-8859-1 |
     awk -F'\\n' '{print "\\gdef\\thisfile{" $1 "\\xspace}"}' >  
tmpfilei.tex
   }
\catcode `\_ 12
\input{tmpdatei.tex}
\input{tmpfilei.tex}
\endgroup
\begin{document}
%\show\directorypath
%\show\thisfile
\directorypath

\thisfile
\end{document}


Some remarks:

  1.  The input-encoding could be  [latin15] or any other, but then  
you would make
      the target (-t) of the  iconv  conversion commands match.


  2.  This also works with [utf8] but beware that you may still need  
a conversion:

              iconv -f UTF-8-MAC -t UTF-8

      This is because for filenames, the Mac OS uses "combining  
umlaut" at ^^cc^^88
      e.g. the filename is:  ha^^cc^^88llo^^cc^^88.tex
      rather than the (cleaner ?)   h^^e4ll^^f6.tex
       \usepackage[utf8]{inputenc}  handles the latter form, but not  
the former.


  3.  My directory path has an _ in a filename.
      This explains the need to  \catcode `\_ 12  before reading   
tmpdatei.tex .
      You need this inside a \begingroup ... \endgroup , which also  
has the \input
      commands. This means that the TeX assignments need to be done  
with the
      (global)  \gdef  command, rather than LaTeX's  \newcommand .
      Other special characters (e.g.  $ % ^ ~ @ # & ) in your file/ 
directory names
      may be handled similarly. ( Braces { } are slightly trickier to  
handle.)


  4.  You can un-comment the  \show  commands, to see (in the Console  
window)
      what you will be getting, before typesetting it.


And a word of warning.
Make sure that your  inputenc.sty  package and support files are  
quite recent.
There have been significant changes since 2002, especially to  UTF-8  
support.
If  \usepackage[utf8]{inputenc}  causes  ucs.sty  to load, then it is  
definitely
time to update.
