Charakter(s) for Line Break in SMS

Hi,

does anyone know what kind of character(s) are used in an SMS - Short
Message for a line break / new line?
Is it a Line Feed (LF) + Carrier Return (CR) or only an LF or only an CR?

I searched for a specification for a SMS but I coulndn't find one.
Hope you can help me.

Cheers,
Michael

A <linefeed>, char(10), character alone seems sufficient in
testing I've done. When preparing a new message, Siemens
phones give you the option of formatting the text (moving to
the beginning of the next line) by adding a "line feed" at any
point. Using this adds only one to the character-used count,
so the <carriage return> seems to be redundant.

Both the <linefeed> and <carriage return> characters are defined
in the 7-bit default alphabet (GSM 03.38).

Update:

I've just proven the above by sending an SMS in PDU-mode using a
single <linefeed> as the newline character. Not only does it
display on the receiving phone's screen as expected, but a PDU
decode shows that user-data field remains unchanged in the
received SMS.
