Lepcha punctuation ta-rol

Ta-rol closes a sentence in Lepcha writing.

Lepcha writing developed under Tibetan influence: early manuscripts were vertical, while later texts were written horizontally.

When older books are reproduced, traditional marks are retained; everyday Lepcha prose uses Western punctuation.

A Tibetan link does not make ta-rol Tibetan

The historical link is between writing systems: ᰻ is a Lepcha mark, not the Tibetan shad (།). In some typefaces their outlines look alike; the resemblance is font-dependent, so check the writing system if the shape is unclear.
