That could be an option. There is already a INVALID_CHARACTER_ERR
exception thrown if the token contains spaces. So I think it would be
consistent to throw an exception if the token is empty, following the
rule "invalid tokens raise exception" (and considering empty tokens as
invalid).

Hard to say, but calling these functions with empty tokens certainly
means there is a bug somewhere and throwing an exception in that case
could help authors identify the issue when it happens.
