#7 Database returns empty strings if they contain non-english (accent or any non-english) chars.

[Carlos Revilla]

When I enter a string in any textbox, when editing or creating a survey/question/answer with any latin character (á-ú, ñ, Ñ, etc), after clicking on "save" the value is stored correctly in MySQL. If I pull the same survey/question/answer later on, the database returns an empty string. Using PhPMyAdmin, I checked and the table in the databaser holds the value, with the latin chars properly stored, but on the source code, there is nothing.

Additional Info:
I tested this on my windows machine, using XAMPP and also in a hostgator server with linux. In both cases, the behaviour is the same: data stored in the database with latin chars won't be shown on the page, the class returns an empty string.
