Comment: 
You don't have to use a character entity, although that may be inferred from the current text in H34. In fact, there are more than one possible issue with that: 


- the editor may not display character entities as you'd expect, due to the bidi algorithm (on the other hand, the editor may make RLM characters visible, like Notepad does, in which case this becomes a better solution) 


- there is a case for using NCRs rather than character entities in XHTML, since it is XML-based and the entities are declared outside the document, and some parsers may not validate when such entities are involved. 


If you keep the example you should probably modify the text to say "Inserting a Unicode right-to-left mark (in this case via the HTML character entityā€¸) ..." or just indicate that characters, entities and ncrs are possible approaches.
