ISSUE:       6064
TITLE:       Field name max length check wrongly if national characters specified
DESCRIPTION:
  Confirmed bug on 3.0.4.32972, got error:
    Statement failed, SQLSTATE = 22001
    arithmetic exception, numeric overflow, or string truncation
    -string right truncation
    -expected length 31, actual 31

  Though this ticket was fixed only for FB 4.x, Adriano notes that error message
  was corrected in FB 3.0.6. Thus we check both major versions but use different
  length of columns: 32 and 64.
JIRA:        CORE-5802
