How to update column by a long char in Oracle12c

Question

I want to update an HTML format, but the HTML format is too long to update. Furthermore, there are functions in this HTML format. it seems that Oracle recognized the characters as the replace() function

UPDATE DS_ADPRODSET_FREETAG
SET html='<script type="text/javascript">
(function(){function c(g){return g.replace(/</g,"&lt;").replace(/>/g,"&gt;").replace(/"/g,"&quot;").replace(/'/g,"&#39;")}function b(h,n){var j={};var l=h.split(n);if(l.length!=2){return j}var m=l[1].split("&");for(var k=0;k<m.length;k++){var g=m[k].split("=");if(g.length==1){j[g[0]]=""}else{j[g[0]]=c(window.decodeURIComponent(g[1]))}}return j}function e(g){var h=/^(http:\/\/i\.yimg\.jp|https:\/\/s\.yimg\.jp)\/images\/listing\/tool\/yads\/yads-iframe.*\.html/;return h.test(g)}var a=(function(){v
ar k="14467902";var j;if(e(window.location.href)){j=window.location.href}else{try{if(e(window.parent.location.href)){j=window.parent.location.href}else{return k}}catch(i){return k}}var g=b(j,"?");if(typeof(g["sid"])!="undefined"&&g["sid"]!=""){return g["sid"]}var h=b(j,"#");if(typeof(h["sid"])!="undefined"&&h["sid"]!=""){return h["sid"]}return k})();var f=(location.protocol=="https:")?"https:":"http:";var d=f+"//yeas.yahoo.co.jp/a?f="+a+"&l=LREC2&p=jp&jcode=u&c=rp&domain=yimg.jp&rnd="+new Date()
.getTime();document.write("<sc"+'ript type="text/javascript" src="'+d+'">');document.write("</sc"+"ript>")})();
</script>'
WHERE adprodset_id=11111;

the Oracle asked me to replace the '&gt', but I just want the contents in XXX are characters.
