Module:Hepburner
Romanizes double vowels per the standard outlined in Hepburn Romanization.
Implemented in Template:Hepburn - Please use this instead of using this directly. It enforces subst for this *very* costly module.
Any double vowels will get converted to a long vowel, ou will get converted to ō.

note: oU aA or the like will break it. You should never, ever, ever do this regardless, but note that is a limitation. If you need that, add it to the list, following the current pattern.
