Mongolian Inverted Birga

It marks a passage opening or the front face of a manuscript leaf.

A folio is one leaf of a manuscript; recto means its front face. The inverted birga is one form in the Mongolian birga family, a kind of Mongolian-script punctuation.

What is the history of the Mongolian inverted birga?

Manuscripts preserve several distinct birga forms.

The Mongolian script grew from the Old Uyghur script, a Central Asian writing system, around the early 13th century during Genghis Khan’s era. Manuscript examples include an ornamented form frequently seen in Mongolian documents, a rotated form attested in archaic texts, and a swirl in a Kalmyk Todo manuscript. Todo is a variant of Mongolian script. Double and triple birgas are also documented in Tibetan sources.

This exact form is encoded as its own character. Older recipes added an invisible display control, such as a variation selector, or a joiner after the regular birga. A 2014 Unicode proposal noted that these sequences were not standardized and had caused compatibility confusion.
