What characters will comprise a carriage return in an html textarea?

For example on my PC it looks like it will use "\r\n"? Could it eve开发者_如何学编程r be something different than that?

Historically it's \r\n on Windows, \r on Mac and \n on *nix. If you take these into consideration you 're golden.

Also: I don't know if this is relevant in your case, but typically many programming languages define a string constant which represents the "native" form of end-of-line for the system they are running on (e.g. PHP_EOL in PHP, Environtment.Newline in C#, etc).

It depends upon the OS I guess, the same old story:

• \n for unix like (and I think OS X too)
• \r\n for windows like
• \r old Apple OSes
