Within the context of Wireshark, no, it doesn't; it suggests, due to the "ephemeral" in the name, that it's
automatically released when dissection is started on a new packet, although, given that most routines
that return ephemerally-allocated memory have just "ep_" at the beginning the name, it should perhaps be
named "ep_tvb_get_unicode_string()" or something such as that to make it clearer. (Yes,
tvb_get_ephemeral_faked_unicode() had "ephemeral", not "ep", in its name, but that was arguably an
error as well. "ep_" should come before "tvb_", as other ephemeral-allocation routines have names that
begin with "ep_", including "ep_tvb_memdup()".)

No - Wireshark doesn't do garbage collection (unless one or more of the extension languages does, and then
it does it only for items allocated in the environment for the extension languages in question, courtesy
of the language's garbage collector). It just does "ephemeral" and "session" allocation, where all
items allocated with a particular lifetime are automatically released in bulk.
