HTML 4.01 Specification
Note. The total number of codepoints
allowed in the document character set of this SGML declaration includes the
first 17 planes of [ISO10646] (17 times 65536). This limitation has been made
because this number is limited to a length of 8 digits in the current version
of the SGML standard. It does not imply any statement about the feasibility of
a long-term restriction of characters in UCS to the first 17 planes. Chances
are very high that the limitation to 8 digits in SGML will be removed before,
and that this specification will be updated before, the first assignment of a
character beyond the first 17 planes.
Note. Strictly speaking, ISO Registration Number 177
refers to the original state of [ISO10646] in 1993.
Changes since 1993 have been the addition of characters and a one-time
operation reallocating a large number of codepoints for Korean Hangul
(Amendment 5). Revisions of the HTML 4 specification may update the reference
to ISO 10646 to include additional changes.
