mysqldump 编码问题

mysqldump  -hlocalhost -uanti -panti anti  --default-character-set=gbk  --socket=/home/admin/mysql/tmp/mysql.sock > /home/admin/anti.sql提示
mysqldump: Character set 'gbk' is not a compiled character set and is not specified in the '/home/admin/u02/mysql/share/mysql/charsets/Index.xml' file
我的数据库是从以前装过的机器上拷过来的，gbk编码是有编译的测试如下：1. 进数据库运行set names gbk，正常，说明gbk编码是存在的、2. [code=SQ]mysql> status
