Either it is useful to have placeholders or it isn't, there isn't one group of people for whom it is useful and another for whom it isn't. Since the main usecase for copying only whitespace is in coding, where the actual number of whitespace characters often is relevant, it appears to make sense to have placeholders.

I think we might change the background color of a char, for example spaces are "marked" green and so on... (Using HTML formatting? I'm not sure what is possible here...) (The point to do this *only* where there are only whitespaces is important!)

Oh, cool - RB screwed it.

Run kcharselect and select "Symbole" and "Symbole für Steuerzeichen" (anybody around not german? =)
There're special glyphs for non-printable characters. I added them to my former post, but RB apparently replaced them w/ nothing :-(

eg. U+2424 (newline) and U+2420 (space)
