Comment (by azaozz):

 @SergeyBiryukov @hellofromTonya @peterwilsoncc I'm actually thinking that
 (most of?) [51984] should be reverted. Removing accents is one thing, but
 removing or replacing characters that change the meaning of the content is
 pretty much "tampering" with the user content. Afaik several languages use
 such non-visible characters and they are integral part of writing.

 To me it seems that the problem in #47912 that was solved with [51984] is
 far less serious. Generally it is quite easy to see when there are
 unneeded or encoded characters in the post slug and to edit the title or
 the slug. On the other hand enforcing removal of characters that the users
 have typed is not appropriate.
