Nitpick: no, from Perl every system uses "\n". But on MSDOS (aka Windows :-)
it's "\0xa\0xd", on Mac it's "\0xd" and on Unix "\0xa". Problems start
when you transfer text files in binary mode from one to another.

ObFWP:

$_="Js nte elhce,\rutaohrPr akr";s/./$&\e[C/g;print;

(works on ANSI terminals at least)

Obreminicence:

As a a sometime user of an ASR33 (aka "teletype") there's a very good
reason for the CR/LF pair. The CR was sent first, and started the print
head moving. Then the LF, which advanced the platen. The CR motion took
longer, so needed a "dead" character after it. Unless you wanted to
overprint, CR-LF did fine. Otherwise you sent CR-NUL.

The decision to use CR+LF as the standard internet line-end is a
puzzling one...
