Try using the following chinese character set (charset):
- big5 | Big5 Traditional Chinese
- gb2312 | GB2312 Simplified Chinese
- gbk | GBK Simplified Chinese
I have checked the above charsets and they are available here.
To change your MySQL Database Charset, Go to phpMyAdmin and then Go to General Setting where you can change what charset that you wanted to use.
Or if you want to change the charset in a specific database, then go to phpMyAdmin and Choose the database that you want to configure and then go to the Operations tab, you can see the option to change your charset there for your specific database.
Hope this helps!
