specified. Both the 4-digit and the 6-digit form can be used to

specify UTF-16 surrogate pairs to compose characters with code

points larger than U+FFFF, although the availability of the

6-digit form technically makes this unnecessary. (When surrogate

pairs are used when the server encoding is <literal>UTF8</>, they

are first combined into a single code point that is then encoded

in UTF-8.)

6-digit form technically makes this unnecessary. (Surrogate

pairs are not stored directly, but combined into a single

code point that is then encoded in UTF-8.)
