'latin1_swedish_ci' is not valid for CHARACTER SET 'utf8'

初始化一个数据库，启动时候报错：

140729 23:56:19 mysqld_safe Starting mysqld daemon with databases from /diskb/mysqldatavdb

140729 23:56:19 [ERROR] COLLATION 'latin1_swedish_ci' is not valid for CHARACTER SET 'utf8'

140729 23:56:19 [ERROR] Aborting

140729 23:56:19 [Note] /home/percona-mysql-5.5.23/bin/mysqld: Shutdown complete

网络上 google 得到的答案是  default-character-set=gbk

可我这里要的是 utf8，想了想，设置系统当前的环境变量：

# export LC_ALL='en_US.UTF-8'

再次启动，ok。
