Bug #21556 federated table - charset=euckr

Description:
federate table didn't support characterset euckr. when servers reconnect between source data and remote data. it didn't display clearly the results of select statements.

server A
CREATE TABLE `test_table2` (
  `id` int(20) NOT NULL auto_increment,
  `name` varchar(32) NOT NULL default '',
  `other` int(20) NOT NULL default '0',
  PRIMARY KEY  (`id`),
  KEY `name` (`name`),
  KEY `other_key` (`other`)
) ENGINE=MyISAM DEFAULT CHARSET=euckr

server B
CREATE TABLE `federated_table2` (
  `id` int(20) NOT NULL auto_increment,
  `name` varchar(32) NOT NULL default '',
  `other` int(20) NOT NULL default '0',
  PRIMARY KEY  (`id`),
  KEY `name` (`name`),
  KEY `other_key` (`other`)
) ENGINE=FEDERATED DEFAULT CHARSET=euckr CONNECTION='mysql://root@localhost:3311/test/test_table2'

server A
shutdown 
# ./mysqladmin -uroot -S /Test/mysql-max-5.0.22/tmp/mysql.sock shutdown 
STOPPING server from pid file /Test/mysql-max-5.0.22/data/shinip.pid
060810 09:54:26  mysqld ended

restart
# ./bin/mysqld_safe --user=mysql &
[1] 19065
# Starting mysqld daemon with databases from /Test/mysql-max-5.0.22/data

server B
mysql> select * from federated_table2;
+----+------+-------+
| id | name | other |
+----+------+-------+
|  1 | ???  |    35 | 
|  2 | ???  |    32 | 
|  3 | ???  |    32 | 
+----+------+-------+
3 rows in set (0.01 sec)

mysql> flush tables;

3 rows in set (0.01 sec)

I don't know reason that this result happened
could anyone tell me the reason? please!!!

How to repeat:
server A
CREATE TABLE `test_table2` (
  `id` int(20) NOT NULL auto_increment,
  `name` varchar(32) NOT NULL default '',
  `other` int(20) NOT NULL default '0',
  PRIMARY KEY  (`id`),
  KEY `name` (`name`),
  KEY `other_key` (`other`)
) ENGINE=MyISAM DEFAULT CHARSET=euckr

insert into test_table2 (name,other) values ('권대성','35');
insert into test_table2 (name,other) values ('박재만','32');
insert into test_table2 (name,other) values ('이용성','32');

server B
CREATE TABLE `federated_table2` (
  `id` int(20) NOT NULL auto_increment,
  `name` varchar(32) NOT NULL default '',
  `other` int(20) NOT NULL default '0',
  PRIMARY KEY  (`id`),
  KEY `name` (`name`),
  KEY `other_key` (`other`)
) ENGINE=FEDERATED DEFAULT CHARSET=euckr CONNECTION='mysql://root@localhost:3311/test/test_table2'

server A
shutdown 
# ./mysqladmin -uroot -S /Test/mysql-max-5.0.22/tmp/mysql.sock shutdown 
STOPPING server from pid file /Test/mysql-max-5.0.22/data/shinip.pid

restart
# ./bin/mysqld_safe --user=mysql &

# Starting mysqld daemon with databases from /Test/mysql-max-5.0.22/data

server B

Thank you for the bug report.

related to bug# 17044. I have committed a patch for 17044 which is patch pending status.

I'm trying to test this to see if my patch fixes this. It does fix it for UTF8. 

I can't even get a myisam table to return results correctly:

I even tried:

   /home/patg/mysql-build/mysql-5.0-engines-bug17044/sql/mysqld --no-defaults --init_connect='SET AUTOCOMMIT=1'   --skip-innodb --skip-ndbcluster --port=5554 --socket=/tmp/fed.sock --datadir=/home/patg/mysql-build/mysql-5.0-engines-bug17044/mysql-test/var/master-data/ --character-sets-dir=/home/patg/mysql-build/mysql-5.0-engines-bug17044/sql/share/charsets --default-character-set=euckr --character-set-server=euckr --basedir=/home/patg/mysql-build/mysql-5.0-engines-bug17044/sql --language=/home/patg/mysql-build/mysql-5.0-engines-bug17044/sql/share/english --log=/tmp/mysqld.log

with these results:
