I have a string in a text area say, Dim 3.0 .030. I have a button on the form that will append a +- symbol to this string. However, I need the symbol to be placed between the 3.0 and the .030 or where ever the cursor is located within the string.

Ok, thanks, I have now got control over where the symbol is inserted. But now I have a new problem. The textarea looks ok but when I submit the textarea text is sent as:

[12/5/07 11:47:17:647 CST] 0000003a SystemOut O Test������

How do I get the A symbols out of the string before it is saved and the last special character should be a theta(String.fromCharCode(248))?

Have you set the correct page encoding?

The jsp I am using has this in the HEAD Section

http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"

The character encoding of the servlet response is:

ISO-8859-1 just like the jsp HTML so I still don't get what is wrong.

Ok, I put:

request.setCharacterEncoding("UTF-8");

in the servlet doGet and it works. Is this the correct way to fix this issue?
