Symbols are not used to write the words of languages, living or
Symbols are not classified as "letters" by anyone I know of and,
in particular, do not have Unicode General Categories "L*".

You may or may not find those distinctions between symbols and
letters in historical scripts persuasive relative to what should
be permitted by the protocol, but I believe it is clear that
they are not the same thing and hence that analogies do not
automatically apply.
