That Wikipedia article is a good discussion of the complicated situation of how to type the non-printing control character for a newline in different OS environments.

But I think what Mary is looking for is exactly the opposite--a *printing* character that indicates a line *continuation* (i.e. that does *not* terminate a ling line in the middle).

In the cases where I've been called upon to do this, I've used character number 191 (0xBF) in the Symbol font, but this approach has two significant shortcomings. First, if the mapping to the Symbol font gets lost for some reason, the character appears as an inverted question mark (the standard mapping for that character number in a text font as opposed to a non-text symbol font). And second, many readers want to be able to copy and paste blocks of code from technical publications rather than having to retype it, and that approach will yield erroneous code if you use a typographic line continuation character.
