 Thanks for the explanation, that makes sense.

  Yes, that's what I thought too, but it doesn't provide a font-independent solution.

  Note that Mojca remarked that using character 10 (LF) produced the desired result in that particular font (Abyssinica SIL).  Is there any reason why one would prefer the former over the latter, or why either of these characters would be a safer bet in general?  I would have thought that both of them, being control characters (sort of), would precisely have no glyph in most fonts; after all, who would want to set a glyph for a character that's supposed to indicate the end of a line of text?
