Probably, but it certainly shouldn't be upper case.

It depends on what the point of this module is supposed to be. Doing
"unaccenting" usefully depends on language and context. For example, it
would be very reasonable to map æ to ae, but in a Scandinavian context,
æ is equivalent to ä, which is mapped to a, which is itself
questionable.

That certainly seems wrong. It's also worth noting that while æ is in
some languages considered a separate letter, œ is generally just a
typographical ligature.
