use of texttops wrapper with nstexttopdf filter on Mac OS X

[Helge Blischke]

As the nstexttopdf filter, which is used by default for printing text files,
seems to accept only Macroman encoded text, the wrapper script needs to be 
additionally modified as follows:

the statement 

binmode (FILO, ":utf8");

must be changed to 

binmode (FILO, ":encoding(MacRoman)");

I've updated the link entry accordingly (it will be publicly available after 
approval by Michael Sweet, I think).
