Hi, Anton: The suggested octet may not seem necessary from sender's perspective. But as Alex pointed out, the receiving end syslog server/application can do the decoding easier with the help of that "encoding type" octet before the structure data and message body.
Besides, this octet can be helpful to allow other encoding not limited to laguages, if needed. And if some specific value out of the octet is reserved, it can help future extension for this specification and help ease the extension related migration issues.
