ID:          issue-6555
ISSUE:       6555
TITLE:       Assigning RDB$DB_KEY to MBCS CHAR/VARCHAR does not enforce the target limit
DESCRIPTION:
  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).
JIRA:        CORE-6314
FBTEST:      bugs.core_6314
