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.

  Bug#18004 Connecting crashes server when default charset is UCS2
  Use of default_charset_info was wrong.
  Functions check_db_name, check_table_name and check_column_name
  get values of system_charset_info character set (utf8).
