Phags-pa Single Head Mark

It marks where a Phags-pa passage begins.

It is not pronounced as part of a syllable. In Tibetan-style Phags-pa, it may stand before a shad, a mark that closes a clause or section. Most Phags-pa texts used no punctuation, so ꡴ is not a universal feature of the script.

Where did the single head mark come from?

It belongs to a Tibetan punctuation tradition within a Mongol imperial script.

At Khubilai Khan's request, the Tibetan lama Phags-pa devised the script for Mongolian, Chinese, and other languages under Mongol rule; it was promulgated in 1269. The script appeared on edicts, monuments, seals, books, and other artifacts before declining outside Tibet after the Yuan dynasty.

A Unicode review from 2004 describes head marks as Tibetan additions found mostly in 19th- and 20th-century Tibetan Phags-pa texts. In one calligraphy page, the double form ꡵ opens the first column while ꡴ starts a continuation column.

Should you send ꡴ by itself?

Only if the recipient expects a script or typography reference.

Alone in ordinary chat, it is not a complete conversational message. A lone mark is best read as a Phags-pa sample or a formatting reference, not an expression of feeling; add words if the context is unclear.
