Here's the problem: I paste the HTML entity code for, let's say, a service mark (
℠) into the HTML view of the editor. As soon as I switch to the "visual" tab, my entity code is turned into an actual service mark character (I guess the corresponding UTF-8 character or something? I don't know from character encodings...). I don't want this--I want it to stay as the entity reference.
Is there some kind of configuration I can change to stop TinyMCE from doing this? My understanding from reading the internets is that this is not the default behavior--that TinyMCE should actually be doing the opposite, and converting characters to their entities. So is this something specific to WordPress' version of TinyMCE?
