Mysql bin log 乱码

   Our system required data sync between each sub system, and it charged by be, last friday I think data sync maybe finished, but at six o'clock before I went to home, I found a problem, The sql from binlog have a problem that it can't display Chinese word right, so it changed the sql structure, sql maybe like this:
update user set id='145', name='乱码?, version='10';
   Our database use innodb and out tables use UTF-8 character set, I search this problem by google and other search engine, but there are less info, it can't help me to solve this problem.
   When go home, I write a test of problem, use mysql 5.0.18

drop table test;
create table test(
name text default null
)engine=INNODB DEFAULT CHARSET=utf8;
insert into test(name) values ("测试");
mysqlbinlog --hexdump E:\programing\Mysql\data\mysql-bin.000001>E:\test.sql
