My code is Encoding.GetEncoding(\"iso-8859-9\"); in my Windows Phone project. But \"iso-8859-9\" is not supported on Windows Phone. How can I fix this problem?<
To use the program, just type the encoding name and it will generate the class like so:

Then make a file for the class somewhere (Copypaste the code generated from the program) and start using it:
//Instead of
Encoding enc = Encoding.GetEncoding("iso-8859-9");
//do this
Encoding enc = new ISO88599Encoding();
//Proceed exactly the same
The code generated is too long to copypaste here but hopefully you manage with these instructions.
