I'm developing a Winforms application that reads some variable values
from a .config file(similar to XML file). Besides, I need to format the
value I read from the config file. I do it this way:

String.Format(ConfigurationManager.AppSettings["Javascript"], "6) //
Want to insert "6" value

I've got this in my .config file:

<add key ="Javascript" value="function GetKey(){key = new
Key('myKey'){0};var i = 'jjj';} " />

First, the encoding of the .config file was set to utf-8, but framework
threw me an error because didn't like single quotes. Then, I changed
the encoding to ISO-8859-1 and single quotes problem was solved. But
another problem has now appeared: don't like both { and } characters.

How can I escape { and } characters? Or maybe a neutral
encoding/escaping method that lets me read all values properly? Is
there any way I can get in my code this "as is":

function GetKey(){key = new Key('myKey')6;var i = 'jjj';}

Please don't know what else I can try........

Thanks very much in advance.
