All Unicode characters are 16 bits wide (well, not strictly
true...), but have a large variety of encodings. In UTF-8, for
instance, the ASCII characters are encoded exactly the same
way, so newline is, er, \n. UTF-7 is just plain silly, and
UTF-16 is 16-bits wide, so newline would be \0\n.
in reply to newline for Unicode?
(Note that the first 256 characters of Unicode are the
ISO-8859-1, character set, better known as Latin-1. The
first 128 are ASCII)
There again, in NT, text files are plain 8-bit ASCII (with
the top-bit set characters being some godawful M$ encoding),
so \r\n should indeed do the trick, unless you really
are using some form of Unicode editor & file format.
(Perl was written for Unix, where newline is just \n, but
NT considers newline to be \r\n. Actually, only notepad
seems to think that these days...)
