This commit implements https://tools.ietf.org/html/rfc2231#section-4 in
order to support sending unicode characters. Tested on both Firefox and
Chromium under Linux.
This adds unidecode as a dependency, which might be relaxed by using
.encode('latin-1', 'ignore') but wouldn't be as useful.
Also, added a test for the correct headers to be added.
Previously, using a filename parameter to send_file with unicode characters, it
failed with the next error since HTTP headers don't allow non latin-1 characters.
Error on request:
