Visual Characters On/Off: This option will enable the Visual Characters On/Off. Usage: I'm pretty speechless on the useage of this feature, so I will quote the words of the kind gentleman who requested it: The small group I am coaching at present in using WordPress are what I call 'people who use computers' as opposed to 'computer users'. They can handle copying and pasting with a mouse, and basic formatting. Being as they don't know CSS and HTML this tool is very handy for showing them why their content isn't displaying as it should. Visual Characters button enabled in the back-end. Visual Characters button enabled in the front end. No difference.
