Ok, got that. Thank you and Peter Dyballa for the replies. Indeed I
had been using TexShop set to use Mac OS Roman (although I am trying
to figure out if I should try to learn using Aquamacs... or maybe
turn to iTexMac... maybe somebody can give me some advice on the
Probably there is little hope to convince my collaborators to use
anything else than Word ... consider myself the most experienced when
it comes to Tex (and if you have read the types of questions I´ve
been asking on that list you get the idea what that means...)
Thanks again for the clarification, I will have to trash some tex-
tutorials that gave me the wrong idea about the inputnec-options.
