jquery – How to remove ​ from wiki pages

I am using SharePoint 2016 wiki library. I have created several pages and they need to have same format. However, in some pages, SharePoint have inserted ​ character at top of page. When browse with Chrome browser it looks like a link break and all the content move down by 1 line.

The problem is this ​ is inserted inconsistently. Some page have &ZeroWidthSpace while some did not. The wiki pages format are inconsistent. I have tried modify the content again and again but couldn’t figure out the pattern of SharePoint insert ​.

How can I work around it? JQuery is acceptable?
