  Bug#7192 Specify --with-collation doesn't work for connections?
  --with-collation worked only on the server side.
  Client side ignored this argument, so collation_connection
  was not properly set (remained latin1_swedish_ci).
  

  sql-common/client.c@stripped, 2006-08-11 13:14:24+05:00, bar@stripped +31 -2
    - Take into account MYSQL_DEFAULT_COLLATION_NAME if
    character set is not set using mysql_option(), to
    honor --with-collation argument to configure.
    - Use default collation for the character set when it's
    not set using mysql_option().
