UAX44-LM2 exceptionally treats the hyphen in “HANGUL JUNGSEONG O-E” as non-medial. character_name_normalize detects that by checking whether the remaining string after the hyphen is E or e. It should also ignore spaces and underscores. For example, "hangul jungseong o-e _" should be canonicalized to "hanguljungseongo-e", not "hanguljungseongoe".
