Yes. StringChar has a synthesized attribute as char and Escapped has
one of string. The result is therefore a variant or char or string.

Also... if this is what you want, why break out the escape character at
all? If you are doing something with it later anyhow I don't see why
you are trying to detect it in the parse.
