Oh, thanks for your quick reply. But I'm Vietnamese, so I have to use Unicode to show content. Everytime I try to submit Unicode character, it converts 2 times so the data display correctly.

For example, when I try to enter the value v? dụ, in database, it should store data as ví dụ , but the current Survey class file parse again the value ví dụ to ví dụ (means it convert & to &amp etc.) before save it to database show the data encoded twice.

Is there any way you could suggest me to solve this problem ?

Thanks in advanced
