True, but
As Oracle UTF8 character set definition supports surrogates by a pairs of
two
3-bytes to be sync with UTF-16 in binary sorting and code point,
This in not a conformant representation.
D29 (p. 46) states that a UTF "transforms each Unicode scalar value into a
unique sequence of code values". Am
You could define a UTF that mapped scalar values below to the same as
UTF-8, and values above to a 6 byte value. It would *not* be UTF-8, but it
can be well defined.
If you look below D29 -- p. 46 at the first full paragraph -- you find that for
round tripping, UTFs are required to map
Title: Oracle and Surrogate Pairs
What is the correct way of supporting surrogate pairs in Oracle 8? Anything wrong with approach of making fields 3 times longer from ASCII or should fields be 4 times ASCII as per UTF-8 spec?

Mikko,
As there is no character defined in
surrogate range in Unicode 3.0, the maximum width for Oracle UTF8 character set
is 3 bytes. Here I recommend you to use 3 times for the number of
characters

True, but within a year or so, there *will* be surrogates assigned in Unicode. One
cannot be premature in supporting them at
