How do I convert escape characters in Javascript to a .txt file?
===

<br /><br />
I have an HTML file that is using Javascript to do file I/O operations on a .txt file, via an ActiveXObject (***only*** works in Internet Explorer, on Windows OS).
<br /><br />
There is a text input box on the HTML page, and a button. The button calls a function &nbsp;`onclick`&nbsp; to write the text entered to the end of the .txt file. There is also a textarea on the HTML page, in which the modified contents of the .txt file are copied and pasted into. All of this is working so far...
<br /><br /><hr />
So, I want to insert tabs and new-lines into the .txt file, from my HTML page with Javascript. I am using this line to copy the .txt file contents into the textarea, initialized in a variable:
<br />

    var newText = oldText + "\n" + document.getElementById("userInput").value;

Of course, the escape character &nbsp;`\n`&nbsp; works on the HTML page, and not in the .txt file...
<br /><br /><hr />
So how do I encode new lines, and tabs as well, into a parsable format for the .txt file? I have tried using the &nbsp;`escape()`&nbsp; method on &nbsp;`ANSI`&nbsp; values [found here][1], and on &nbsp;`ASCII`&nbsp; values [found here][2], but with no luck.
<br /><br />
Here is my code so far:
<br />

    <!DOCTYPE html>
    <html>
    	<head>
    		<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    		<title>New Web Project</title>
    	</head>
    	<body>
    		
    		<p>
    			Enter some text here: &nbsp;
    			<input type = "text" id = "userInput" />
    		</p>
    		
    		<input type = "button" value = "submit" onclick = "main();" />
    		<br />
    		<hr />
    		<br /><br /><br />
    		<textarea id = "textHere" rows = 25 cols = 150></textarea>
    
    		<script type = "text/javascript">
    		
    			// executes all code from this function to prevent global variables
    			function main()
    			{
    		    	var filePath = getThisFilePath();
    		    	
    		    	var fileText = readFile(filePath);
    		    	writeFile(filePath, fileText);
    		    	
    			} // end of function main
    		
    		    function getThisFilePath()
    		    {
    				var path = document.location.pathname;
    				
    				// getting rid of the first forward-slash, and ending at the last forward-slash to get rid of file-name
    				var correctPath = path.substr(1, path.lastIndexOf("/") );
    				
    				var fixedPath = correctPath.replace(/%20/gi, " "); // replacing all space entities
    				
    				return fixedPath;
    		    } // end of function getThisFilePath
    		    
    		    function readFile(folder)
    		    {
    		    	var fso = "";
    		    	var ots = "";
    		    	var oldText = "";
    		    	
    		    	try
    		    	{

    			    	ots = fso.OpenTextFile(folder + "writeToText.txt", 1, true);
    			    	
    			    	oldText = ots.ReadAll();
    			    	
    			    	ots = null;
    			    	fso = null;
    		    	}
    		    	catch(e)
    		    	{
    		    		alert("There is an error in this code!\n\tError:  " + e.message);
    		    		exit(); // end the program if there is an error
    		    	}
    		    	
    		    	return oldText;
    		    	
    		    } // end of function readFile

    			    	ots = fso.OpenTextFile(folder + "writeToText.txt", 2, true);
    			    
    				    ots.Write(newText);
    			    	ots.Close();
    			    
    			    	ots = null;
    			    	fso = null;
    		    	}
    		    	catch(e)

    		    	}
    		    	
    		    	setText(newText); // with the function below
    			    
    		    } // end of function writeFile
    		    
    		    	// called from the function writeFile

    		</script> <!-- end of javascript -->
