Stabilized Technical Report
UTR #26, "Compatibility Encoding Scheme for UTF-16: 8-Bit (CESU-8)"
has been stabilized:
There are no plans to ever publish another update for it.
The last version can be found at
CESU-8 documents an obsolete internal-use encoding scheme for Unicode
identical to UTF-8 except for its representation of supplementary characters.
In CESU-8, supplementary characters are represented as six-byte sequences
rather than four-byte sequences.
CESU-8 is not intended nor recommended as an encoding used for open information exchange.
Therefore, there is no need to develop this report any further.
