On Windows files will usually have line breaks build by the sequence 
"\r\n". When reading such a file in normal mode, the "\r" will be 
deleted and not inside the String. When writing data to a file, each 
"\n" will be replaced by "\r\n".

When using "rb" or "wb" on Windows, the data will be unchanged.

On Linux/OS X the line break character in a file is "\n", so the "b" 
mode doesn't have any effect.
