It is a very good idea to have a line and paragraph separator in
Unicode. But I expect that due to compatibility issues, the old
conventions (CR/LF/CRLF) will be used for a rather long time,
even after UNicode has gained much popularity.

Email has very strict restrictions on this. You can't send doublebyte
UTF-16 or UCS-2 in Email. CRLF always has to be present as a line
separator. Unicode in Email is possible with UTF-7 (and CRLF as line
separator) or UTF-8 + BASE64/QuotedPrintable (and CRLF...).
Please see RFC 2045/6/7 for this.
