Add warning for BIDI characters in page renders and in diffs (#17562)

Browse source 
Fix #17514

Given the comments I've adjusted this somewhat. The numbers of characters detected are increased and include things like the use of U+300 to make à instead of à and non-breaking spaces.

There is a button which can be used to escape the content to show it.
