Windows, Linux/Unix and Mac have different line-endings on text files.

A quick overview on the endings are:

• Windows-style line endings are CRLF ( \r\n or hex 0D0A )
• Mac-style line endings are CR ( \r or hex 0D )
• Unix-style line endings are LF ( \n or hex 0A )

A HEX editor can be used to double check that the correct endings are written.
