What does "standard communication protocols are built around octets rather than nonets" mean? Is this an assertion that there are no standard protocols for computers with 9-bit bytes, such as the PDP-10? —Preceding unsigned comment added by (talk) 11:09, 20 July 2007

A protocol that requires 9-bit bytes isn't likely to become a standard. 9-bit machines on the Internet use the same octet-based protocols as everyone else, generally with some adaptation. FTP, for instance, can operate in text mode, unpacking characters into an octet each, or image mode, packing 2 36-bit words into 9 octets. Yuubi 20:26, 11 October 2007 (UTC)

There is another encoding called "UTF-9"(draft-abela-utf9-00.txt) aim for similar target. Roytam1 (talk) 12:04, 2 May 2010 (UTC)

Indeed, that's a rather silly comment, since the whole point of these UTFs is for use on 9-bit, 18-bit and 36-bit systems. I think the only reason someone thought it funny enough for 1 April is that these machines are obsolete, though they (and hence UTF-9 and UTF-18) might be of interest to retrocomputing enthusiasts and esolangers. Obviously you wouldn't seriously use them on octet-based systems - you'd use UTF-8, UTF-16 or UTF-32. As such, I'd be inclined to reword the comment, if not remove it. I'll see what I can come up with. — Smjg (talk) 01:01, 4 September 2013 (UTC)


UTF-12 has been invented recently, too. See it here. — Monedula (talk) 11:29, 17 June 2010 (UTC)

Looks like someone's personal invention, not a standard, so probably not worth covering in Wikipedia for now. -- intgr [talk] 14:38, 17 June 2010 (UTC)
