Faster without Jquery. You can encode every character in your string:

function encode(e){return e.replace(/[^]/g,function(e){return"&#"+e.charCodeAt(0)+";"})}

Or just target the main characters to worry about (&, inebreaks, <, >, " and ') like:

function encode(r){
return r.replace(/[\x26\x0A\<>'"]/g,function(r){return"&#"+r.charCodeAt(0)+";"})
}

test.value=encode('Encode HTML entities!\n\n"Safe" escape
