I'd be happy to donate it under the MIT/X11 license, but it should be
documented as "as a convenience for debugging; please do not define your
D-Bus API in terms of this function".
It's also worth noting that it's pessimal (the opposite of optimal) for
multilingual text - it will expand each UTF-8 character into at least 6
bytes. When transporting D-Bus over Tubes, we need to convert XMPP chatroom
nicknames into unique bus names, for which we use a much more elaborate
nearly-reversible encoding involving (but not limited to!) Base64.
: reversible up to a certain nickname length, after which it falls back
to truncating what it would have produced and appending a hash of the nickname,
in order to fit into the length limit of a D-Bus name
