isCommonIndicNumberForm function

bool isCommonIndicNumberForm(
  1. int rune
)

Common Indic Number Forms (U+A830..U+A839): historic fractions and marks for currency/weights/measures. No phonology; canonical output preserves them and Plain/Hunterian views carry them through untouched.

Implementation

bool isCommonIndicNumberForm(int rune) => rune >= 0xA830 && rune <= 0xA839;
