ISSUE:       6652
TITLE:       Error message "expected length N, actual M" contains wrong value of M when
  charset UTF8 is used in the field declaration of a table
DESCRIPTION:
  All attempts to create/alter table with not-null column with size that not enough space to fit default value must fail.
  Length of such column can be declared either directly or via domain - and both of these ways must fail.

  All failed statements must have SQLSTATE = 22001.
  Confirmed wrong result on 4.0.0.2225: some statements failed with SQLSTATE=22000 (malformed string),
  some issue wrong value of "actual M" for length.
JIRA:        CORE-6414
FBTEST:      bugs.core_6414
