Hi When you enter a '\' into the wysiwyg editor it doesn't render right in the normal view and converts it to '\' in the wikicode which it then treats and an escape sequence. The stopgap is that we use \ in the wikicode, but this isn't very good for low tech users. Any plans to alter this in future releases, and better yet, a quick fix I could implement in the MCE code (im not much for javascript)
