in jQuery I was wondering if there is a function that will convert the following string into
html friendly characters

var myString="@£¥®©®";

but using jquery it will convert that string to the following

@£¥®©®

So basically any Symbol in a string would get converted into the HTML friendly characters

Here is the chart below

But it would be great if you can replace any non numeric or alpha characters with html friendly

Not all of them have a "friendly" name, but all have a numeric code. Not sure why you want the friendly name, when the numeric entities will achive the same thing for a wider number of characters. IF you truly want the friendly names option then update the previous post:
        var searchFor="&,@,£,¥,®,©";
        var replaceWith="amp,pound,yen,reg,copy";

with the characters you want to replace. (BTW: remove @ from the searchFor list). Just to clarify, if you choose to go with the numeric codes, then £ would be converted to &#163; instead ot &pound;. If you were to work with xml, then &pound; would NOT be recognized automatically. You would need to declare it first. However, numeric entities work without having to take extra steps.

If I understand you correctly, you want Letters and Numbers to be left alone, but encode everything else. If so, use:
function numeric(str)
{
	var i=-1,limit=str.length;
	var result="";
	while(++i<limit)
	{
		if( /[0-9a-zA-Z]/.test( str.charAt(i) ) )
		{
			result+=str.charAt(i)
		}
		else
		{
			result+= "&#"+str.charCodeAt(i)+";"
		}
	}
return result;
}
