I think that 0xd9d9f6 or 0xd9d9f8 could be used for CBOR Sequence, and it would also not be valid UTF-8. While "0xd9" is a valid first byte of a three byte sequence, 0xd9 is not a valid second byte. -- ] Never tell me the odds! | ipv6 mesh networks [ ] Michael Richardson, Sandelman Software Works | IoT architect [ ] mcr@sandelman.ca http://www.sandelman.ca/ | ruby on rails [
