There is a soft connection character among the entity characters of html. This character has no representation on the page. But he is a very useful character.
Give a useful example. For example, when we want to filter the events onclick, onmousemove and script object tags in HTML, we can use simple replacements to filter without damaging the user's performance.
As long as you replace it with onclick onmousemove script object, all these events and tags will be invalid
