If you are reading from a file in Windows, Ruby will convert the "\r\n" 
sequence to a single "\n".

Because this can cause trouble when working with binary data or when 
using direct positioning one can open a file for binary processing, 
simly by adding a "b" character to the type of opening the file (see 
documentation for details).

When working with a file opened in binary mode, each line ends with 
"\r\n".
