ISSUE:       6797
TITLE:       Functions DECRYPT and RSA_DECRYPT return VARCHAR CHARACTER SET NONE instead of VARBINARY (VARCHAR) CHARACTER SET OCTETS
DESCRIPTION:
    As of current FB 4.x doc, following is wrong: "Functions return ... *varbinary* for all other types."
    (see note by Alex in the tracker, 11.05.2021 11:17).
FBTEST:      bugs.gh_6797
NOTES:
    [13.12.2023] pzotov
        Added 'SQLSTATE' in substitutions: runtime error must not be filtered out by '?!(...)' pattern
        ("negative lookahead assertion", see https://docs.python.org/3/library/re.html#regular-expression-syntax).
        Added 'combine_output = True' in order to see SQLSTATE if any error occurs.
