Can use atob and btoa which uses base64 encoding and decoding.

<script>
    var scr = "function sample() {}";
    var jsCodeToEmbed = btoa(scr);
    var oScript = document.createElement("script");
    oScript.language = "javascript";
    oScript.type = "text/javascript";
    oScript.text = atob(jsCodeToEmbed);
    document.getElementsByTagName('body').item(0).appendChild(oScript);
</script>

But yes this will use different encoding scheme than you had expected
