What ㉼ means
It marks reference material.
The earliest documented trail is KPS 9566-97, a 1997 North Korean character standard. Its chart was registered as ISO IR 202 in 1998. A 2000 proposal describes use of the set in formal documents and databases, where one enclosed sign printed and displayed cleanly. Unicode included it in 2003.
