component privilege priv_abbr chars not consistent

[Paul Low]

The abbreviation characters allowed in for a component privilege is not consistent with the allowed characters for statements that are listed as only ISO8591 characters.

Syntax:
CREATE COMPONENT PRIVILEGE priv_name AS 'priv_abbr' ON name;
priv_abbr must be in ISO8591 character set.

register user user1 as "^dd";
will return an error, but
create component privilege abcd as ‘^d’ on aa;
will succeed unexpectedly.
