An error message is displayed on the main interface! But you can insert data into the data table!

The data I entered is: My name is 116 170, but the data table is displayed :? Ó ???? 116 170

Why?
------ Best solution --------------------
Why not post the error message?

Mysql_query ("set names gbk"); // execute this statement before insertion.
