If you can't think of a someone to not want it, you should just enable
it. Common reasons to not want it are substantial impact on build-time,
additional dependencies, unsupported or poorly supported upstream,
experimental status, and so on.

Most of the time, one of these applies for these flags, and it's
therefore useless. Hence https://github.com/pkgcore/pkgcheck/issues/414.

Note further that USE=unicode is forced on for many packages in profiles
and historically it ended up changing ABI for a bunch of them.

If you conclude that there is a valid reason to toggle it, then the
next part becomes relevant:

There are real times when we may want to suppress the
warning/notices. This is tracked as
https://github.com/pkgcore/pkgcheck/issues/478
for pkgcheck.
