[racket] Scribble document with accented characters

For the (search engine) record:

No matter what I did, I couldn't get Aquamacs to take seriously my
request to put the file in UTF-8 format. So I switched from editing in
Aquamacs to editing in DrRacket to put on accented character in. When
I reloaded the file, Aquamacs was happy to edit in UTF-8, and I didn't
even need to use string-normalize-....

Everything is perfect now, and I can give proper attribution to my
co-authors from Università della Svizzera Italiana and University of
Jyväskylä.

Thanks DrRacket!
