BBC Code is redundant - bulletin board code code (kinda like ATM machine would literally mean automated teller machine machine). It's just BBCode, and if you say BBC you're talking about a British TV channel. More on topic, I don't think this is possible without a client-side mod, and if you want it to be polished you might need an engine change. The only way I can think to do it is to save a .html file and have the client open that, but I don't really know very much on this topic so if someone wants to correct me go ahead.
