One such symbol is already encoded, the Halmos tombstone U+220E END OF
PROOF. I'm not sure that it should have general class Sm instead of
Po - Paul Halmos himself wrote of the symbol,

"The symbol is definitely not my invention — it appeared in popular
magazines (not mathematical ones) before I adopted it, but, once again,
I seem to have introduced it into mathematics. It is the symbol that
sometimes looks like â–¯, and is used to indicate an end, usually the end
of a proof. It is most frequently called the 'tombstone', but at least
one generous author referred to it as the ‘halmos’."

There are several other such characters already, such as U+0E5B THAI
CHARACTER KHOMUT and U+17DA KHMER SIGN KOOMUUT.
