The incorrect capitalization made me think that, perhaps, there's a scarcely known escape sequence \N that is different from \n. Maybe it matches any character that isn't a newline? Nope, just small caps in the original article.
.title {
font-variant: small-caps;
} Whence '\n'?Many systems use \N in CSVs or similar as NULL, to distinguish from an empty string.
I figured this is what the article was about?
'\N{PILE OF POO}'
Much more self-documenting than doing it with a hex sequence with \u or \U.
