table.cc:
  Fixing to use system_charset_info instead of default_charset_info.
  Crash happened because the "ctype" array is empty in UCS2,
  and thus cannot be used with my_isspace().
  The reason why UCS2 appeared in this context was because of
  of default_charset_info variable incorrectly substituted to my_isspace().
  As functions check_db_name(), check_table_name() and check_column_name()
  always get values in utf8, system_charset_info must be used instead.
