可以初始化表的时候设置utf8，适配数据库不是utf8的人

1. Go to './cmd/migrate/migration/version/1599190683659_tables.go'
2. Scroll down to '1599190683659_tables.go:20'
3. err := tx.Set("gorm:table_options", "ENGINE=InnoDB DEFAULT CHARSET=utf8").Debug().Migrator().AutoMigrate(
   new(models.CasbinRule),
   new(models.SysDept),
   new(models.SysConfig),
   new(models.SysTables),
   new(models.SysColumns),
   new(models.SysMenu),
   new(models.SysLoginLog),
   new(models.SysOperaLog),
   new(models.SysRoleDept),
   new(models.SysUser),
   new(models.SysRole),
   new(models.SysPost),
   new(models.DictData),
   new(models.DictType),
   new(models.SysJob),
   new(models.SysConfig),
   new(models.SysApi),
   new(models.TbDemo),
   )
