 > What are the steps to reproduce the problem?
 "Non` `visible char" you can copy-paste this text in the post title and
 can notice the permalink for some encoded chars or copy-paste some non-
 visible chars form https://www.utf8-chartable.de/unicode-
 utf8-table.pl?start=8192&number=128 in the title.

 > Are there any testing dependencies such as a plugin or script?
 There are no dependencies for this.

 > What is the expected behavior after applying the patch?
 When we paste these non-visible chars in the title, it should be removed
 and save only the valid chars.
