DeScribe Word Processor has (had? it hasn't been developed in about a decade... but it still runs just fine) a whole lot of visual guides for metacharacters, which can be turned on or off. Normally, we prefer not to have a little dot to mark every 0x20 space, but you can have 'em if you want 'em; tabs get shown as diamonds; paragraph markers as pilcrows; line breaks as a small circle; and so on. (The difference between a paragraph and a line break isn't a normal one in most text editors, so I'd be looking at representing U+000A newlines with a pilcrow, probably.) Obviously you need a means of distinguishing the end-of-line marker from an actual character, since PILCROW SIGN is a perfectly acceptable character; but if the metacharacters are shown in, say, a pale blue, rather than the usual black text, it'd be easy enough.
