我有一个拉丁文和瑞典语的ci数据库，里面有utf-8字节字符，显示为%c5%a1，%c4%8d，。。。
我已经将数据库和表从latin1转换为utf8，但仍然需要修复utf-8字节字符。

ALTER DATABASE databasename CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;
ALTER TABLE tablename CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

mysql默认字符集：

SHOW VARIABLES LIKE  'char%'

character_set_client    utf8mb4 
character_set_connection    utf8mb4 
character_set_database  utf8mb4 
character_set_filesystem    binary  
character_set_results   utf8mb4 
character_set_server    latin1  
character_set_system    utf8    
character_sets_dir  /usr/share/mysql/charsets/

我尝试了mysql函数但没有成功：

convert(cast(convert(name using  latin1) as binary) using utf8)

我真的需要帮助！谢谢您。
