The Rich text editor in Sharepoint 2013 inserts “zero width spacing” characters when editing HTML. Unfortunately, these are not visible to the normal user and so it is difficult to remove, so much for WYSIWYG!
Below is a Javascript snippet that will remove all instances of the character in the HTML field’s editable region.
//insert this script in the <head> after
<SharePoint:ScriptLink language="javascript" name="core.js" OnDemand="true" runat="server" Localizable="false"/>
EnsureScript('SP.UI.RTE.js', typeof (RTE), function () {
//Removes ZWSP characters
if (RTE.Cursor.update == undefined)
return;
try {
var update_orig = RTE.Cursor.update;
RTE.Cursor.update = function () {
update_orig();
var range = RTE.Cursor.get_range();
if (range.isValid()) {
var editorElement = RTE.Canvas.getEditableRegion(range.parentElement());
if (editorElement && editorElement.innerHTML) {
editorElement.innerHTML = editorElement.innerHTML.replace(/u200B/g, "");
}
}
}
} catch (e) {
console.log (“RTE override error”, e);});
