				Why do you want to substitute the special characters to named entities?

 In my case, it is a mixture of what DiapDealer replied

 and the wish to be able to easily find and replace my *really special* characters, such as those fleurons I mentioned above from the "private usage area." When you are using entities like 
& # xf021;  and & # xf029;  and & # 61477; 
it helps to be able to see the actual codes instead of just a generic missing-glyph character, when I want to replace one or more of those with a different decorative character. 
Not all "special character" entities convert automatically to the actual character if they depend on a special or embedded font that is not availabe to the code editor.
PS-- And I *still* wish we could search in book view, like the old versions.  It was the fastest simplest way to find stray straight-quote marks that fell in the text outside of tags. Now you have to mess around with regex to hunt them down.
