GTM自定义HTML x26

Question

在GTM中以自定义HTML格式上传以下脚本时

我注意到＆更改为\ x26，=更改为\ x3d-想知道如何上传上述脚本并保留特殊字符。

<script type='text/javascript'>
function loadScript(url, callback){
var script = document.createElement("script")
script.type = "text/javascript";
if (script.readyState){ //IE
script.onreadystatechange = function(){
if (script.readyState == "loaded" || script.readyState == "complete"){ script.onreadystatechange = null; callback(); }
};
} else { //Others
script.onload = function(){ callback(); };
}
script.src = url;
document.getElementsByTagName("head")[0].appendChild(script);
}
loadScript("https://pro.pocketmath.com/js/pmct_conversion.js", function(){__PMCT_CE_CONVERSION.init("&ce=49c6fc104f5d_10&awin=ct30")});
</script>
