/* Hind Siliguri has a documented malformed glyph for Bengali digit ১ (U+09E7) in its
   regular/medium/semibold/bold weights. Rather than swap the whole font (everything

   runs that contain ১ (e.g. "১০", "১২") and reroutes just that run to Noto Sans Bengali,
   so a run like ৳১০ doesn't mix two different digit styles mid-number. See bn-digit-fix. */
