I have yet to work on a project where neither charsets nor line-endings ever pop-up and cause problems... seeing as it is 2011, this is an absolutely abysmal testimony for IT as a whole.
It just happens that we ended up in a world where basically everything is Unix or Windows, so Windows seems like the odd man out. But history tells a rather different story. The use of CRLF was enshrined in RFC561 (the original email RFC) in 1973, before Unix was popular.
