# title:        Assigning RDB$DB_KEY to MBCS CHAR/VARCHAR does not enforce the target limit
# decription:   
#                  In order to prevent receiving non-ascii characters in output we try to get only octet_length of this.
#                  Confirmed bug on 3.0.6.33289, 4.0.0.1954 (get result = 2 instead of raising error).
#                  Checked on 3.0.6.33294, 4.0.0.2000 - works fine.
