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 ?
