Below is Ken Whistler's historical table of codespace counts, extracted from
the message "Is 879,309 enough?" and slightly refurbished, followed by the
Unicode 3.2 codespace allocation map (cf. http://www.unicode.org/roadmaps ).
Your terminology may differ, but here's what's used below:
BMP = Plane 00, the Basic Multilingual Plane
Suppl = Plane > 00, the Supplementary planes
Area = as defined in Unicode 3.0 (though non-normative)
Assgnd = Assigned to a character in Unicode 3.2
Rsrvd = Reserved for special usage, can never be assigned to a
character
Unasd = Unassigned in Unicode 3.2, available for future assignment
