UCS2 / Unicode encoding

A UCS2 or Unicode encoded message can have a length of max 70 unicode characters (fyi, each one is worth 2 bytes). If you put more characters in, the message will be split up into several parts. This kind of message is called long message or concatenated message. Each part can of a concatenated message can consist of 67 characters at max. This shorter amount is due to the fact, that the other 3 unicode characters are “eaten up” by informational bytes which tell the end user device that its a concatenated message and further information, like total part count, current part count, etc…
