[Pharo-project] return character magic?

Hi all, Just last week, I had a very strange phenomenon in my Pharo image: the return character (^) was changed by an up arrow (see screenshot below). I was not really able to reproduce the 'problem' but now we got a repeatable one: Just load the attached js file in a Seaside WAFilelibrary (WAFilelibrary addFileAt: ' ...'): you will see that the method will also have such a return char. What is going on? :-) I'm on Mac, using Pharo 1.1. cheers, Johan A MIME attachment of type <application/x-javascript> was removed here by a drop-attachments-by-name filter rule on the host <mail2-relais-roc.national.inria.fr>.
