Re: Backslash n [OT] was Line Separator and Paragraph Separator

[Andy Heninger]

Unicode UAX 14 (Line Breaking Properties) also has a bit to say on this 
topic of line separators

From http://www.unicode.org/reports/tr14/

BK - Mandatory Break (A) - (normative)

Explicit breaks act independently of the surrounding characters.

000C
        
FORM FEED
Form Feed separates pages. The text on the new page starts at
> the beginning of the line. No paragraph formatting is applied.
2028
        
LINE SEPARATOR

The text after the Line Separator starts at the beginning of the line.
> No paragraph formatting is applied.
This is similar to HTML <BR>

2029
        
PARAGRAPH SEPARATOR

The text of the new paragraph starts at the beginning of the line.
> Paragraph formatting is applied.
“NEW LINE FUNCTION (NLF)”

New line functions provide additional explicit breaks.

Mandatory breaks:

LB 3a  Always break after hard line breaks (but never between CR and LF).

BK !

LB 3b  Treat CR followed by LF, as well as CR, LF and NL as hard line breaks

CR × LF
CR !
LF !
NL !
