It's interesting to read the April Fool's RFC1606, which was written a little over 20 years ago, and see references to light switches and lightbulbs with IP addresses.
"IP address urgent needs caused by natural question of how to introduce IPv6, although other new industry solutions IPv9 IP addresses, etc. are also emerging, but IPv6 is still by far the most practical, the most sophisticated methods" [1]
Very distinct than the "chinatechnews.com" statement [2]. Just plain poor journalism.
The worst thing about UTF-7 is that it has multiple valid representations of the same string.
I'm convinced that the primary use of UTF-7 is hiding malicious input as different characters [1], as a possible exploit against systems that support UTF-7 for no reason.
That would be a bit of an overkill now, 1 parity bit for every 8 bits of information? Also, text is a representation format, not a transfer/storage format, so I reckon it's not really the job of the character encoding to do error detection.
Yes, I know, I'm taking this way too seriously. :)
