Use The Pos property to set the position of the cursor. To solve your problem, 
just set the cursor to the end of the text before calling Insert:

MyTextArea.Pos = MyTextArea.Length
MyTextArea.Insert("text")

Moreover, you must use UTF-8 String methods to deal with the contents of any 
GUI Text property.

I suggest you read the documentation of the TextArea widget carefully!
