The idea is that there would be an additional UTF format, perhaps UTF-64, so that each character would be expressed in UTF-64 notation using 64 bits, thus providing error checking and correction facilities at a character level.
I think this proposal is a few weeks early, and that it should be resubmitted on the proper date, but as UTF-256 - for greater redundancy.
UTF-256 allows each hex digit of UTF-32 to be expressed as an ASCII hex digit (characters 0-9 and A-F encoded as bytes 0x30-0x39 and 0x41-0x46).
This leaves two bits per hex digit unused which could be utilized for bit-level error correction, or you could go to UTF-512 and encode each code twice.
The possibilities are endless. A./
