mysql的乱码问题

ALTER TABLE `news`.`snapshots` MODIFY title VARCHAR(1024) CHARACTER SET utf8; 

    ALTER TABLE `news`.`snapshots` MODIFY source VARCHAR(50) CHARACTER SET utf8;

    ALTER TABLE `news`.`snapshots` MODIFY NAME VARCHAR(100) CHARACTER SET utf8;

    ALTER TABLE `news`.`snapshots` MODIFY place VARCHAR(1000) CHARACTER SET utf8;

    ALTER TABLE `news`.`snapshots` MODIFY b1 VARCHAR(500) CHARACTER SET utf8;

    ALTER TABLE `news`.`snapshots` MODIFY b2 VARCHAR(500) CHARACTER SET utf8;

    ALTER TABLE `news`.`snapshots` MODIFY b3 VARCHAR(500) CHARACTER SET utf8;
