Unidecode 1.3.5 (a yanked PyPI version) changed the behavior of
Unidecode for some specific characters:

> Remove trailing space in replacements for vulgar fractions.

As luck would have it, our tests used the 1/2 character specifically to
test the behavior when these characters decoded to contain slashes. We
now pin a sufficiently recent version of Unidecode and adapt the tests
to match the new behavior.
