ー (long-vowel mark) expands incorrectly after katakana ヒ and ビ
normal-jp · birchill/normal-jp
Symptom
During normalization, the chōonpu (ー) is expanded with the wrong vowel after katakana ヒ and ビ.
Minimal repro
Normalize ヒー / ビー; the long-vowel expansion produces the wrong vowel for these two kana.
Fix
Fix the ー-expansion table entries for ヒ and ビ.
