SHOW TABLE STATUS and SHOW CREATE TABLE occurs messy code

[dwwang1992]

The target database is utf8 character set, when i look the page Create Table Statements and Table Status,the chinese comments occurs messy code, as follows:

CREATE TABLE tb1 (
id varchar(512) DEFAULT NULL COMMENT '????',
res_name varchar(128) DEFAULT NULL COMMENT '????',
res_module varchar(128) DEFAULT NULL COMMENT '????',
res_id int(10) NOT NULL AUTO_INCREMENT COMMENT '??id',
method varchar(128) DEFAULT NULL COMMENT '????',
PRIMARY KEY (res_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COMMENT='???'

what should i do something to avoid messy code ?
