The wildcard characters * and # only match on whole words, so a pattern
like publish.A# is not valid. You can get around this restriction by
structuring routing keys to contain the first and last letters as
separate words, e.g.

publish.A.B.absorb
publish.C.D.candid

and to create bindings for all the patterns that start with A but don't
end with B:

publish.A.A.#
publish.A.C.#
publish.A.D.#
...
publish.A.Z.#
publish.A.0.#
...
publish.A.9.#
