Nothing too smart. It doesn't know what language it is, or even how to
separate words, so simple questions like should don match don't, or
should don match donut, or should don match @don# (where @ and # are
equally mysterious PUA code points) are impossible to answer. It could
be Verdurian (http://www.evertype.com/standards/csur/verdurian.html) ,
for all Google knows. PUA is completely inscrutable in such a
situation, until it becomes a case like U+0093 and U+0094, where
everyone knows they're really quotes even though Unicode says
otherwise ... which is a hideous pain for everyone.
