Group 00 is an ISO 10646 (not Unicode) term for the character
codes in the range 00000000 to 00FFFFFF. Since all codes
that will ever be used in pracice extend only as far as 0010FFFF,
Group 00 means the whole thing.

Technically, the codes 00E00000-00FFFFFF (2,097,151 codepoints) and
60000000-7FFFFFFF (536,870,911 codepoints) are available for private
use, but no one will ever use them: the existing private-zone areas
are sufficient.
