It's a bit tricky when the reason is that it was too hard to get users
of English to make a distinction between U+02BC and U+2019.  And for
Larry Niven's elephant-like aliens in _Footfall__, is _fi'_, the
singular of _fithp_, better written with U+02BC or U+2019?  And does
the phonetically faithful spelling of Estuarine English _fi'_ for
_fit_ depend on whether the glottal stop is dropped?

The science-fiction ethnonym _Vl'harg_ is also tricky.  Does its elegant
encoding depend on whether the apostrophe is a vowel symbol (so
U+02BC) or the indication of an omitted vowel (so U+2019)?
