DESCRIPTION:
  It was found that error raises in 2.1.0.17798 when we create table with two fields
  of UNICODE_FSS type and add there six rows. Content of fields were taken from table
  rdb$procedure_parameters of empty database.
  Data that are inserted have been found after several simplifications of source DB.
  Exception that raised:
    Statement failed, SQLCODE = -802
    arithmetic exception, numeric overflow, or string truncation
