U+1DA8A "𝪊" Signwriting Colon Unicode Character

U+1DA8A "𝪊" Signwriting Colon is a typographic symbol used in the SignWriting script to represent a specific pause or rhythmic break in the written form of sign languages. Unlike a standard punctuation colon, this character functions as a grammatical marker within SignWriting notation, typically indicating a brief separation between signed phrases or concepts. It is encoded in the Sutton SignWriting block of Unicode, which was added to support the systematic written representation of sign languages, and it visually resembles two small stacked dots, but is distinguished from ASCII or colon punctuation by its unique orthographic role.
