... I forgot to mention that some of the math characters are NOT in the range given above (because they existed previously and are left in their original position instead of duplicating them in the new math range). Also, 4 additional code points are not used (reserved) These are:

Valid code point	Character	Name	Invalid code point	Comment
U+210E	ℎ	planck constant	U+1D455	despite the name ("planck constant"), it is also used as "mathematical italic small h"
U+212C	ℬ	script capital B	U+1D49D	"script ..." = "mathematical script ..."
U+2130	ℰ	script capital E	U+1D4A0
U+2131	ℱ	script capital F	U+1D4A1
U+210B	ℋ	script capital H	U+1D4A3
U+2110	ℐ	script capital I	U+1D4A4
U+2112	ℒ	script capital L	U+1D4A7
U+2133	ℳ	script capital M	U+1D4A8
U+211B	ℛ	script capital R	U+1D4AD
U+212F	ℯ	script small e	U+1D4BA
U+210A	ℊ	script small g	U+1D4BC
U+2134	ℴ	script small o	U+1D4C4
U+212D	ℭ	black-letter capital C	U+1D506	"black-letter ... " = "mathematical fraktur ..."
U+210C	ℌ	black-letter capital H	U+1D50B
U+2111	ℑ	black-letter capital I	U+1D50C
U+211C	ℜ	black-letter capital R	U+1D515
U+2128	ℨ	black-letter capital Z	U+1D51D
U+2102	ℂ	double-struck capital C	U+1D53A	"double-struck ... " = "mathematical double-struck ..."
U+210D	ℍ	double-struck capital H	U+1D53F
U+2115	ℕ	double-struck capital N	U+1D545
U+2119	ℙ	double-struck capital P	U+1D547
U+211A	ℚ	double-struck capital Q	U+1D548
U+211D	ℝ	double-struck capital R	U+1D549
U+2124	ℤ	double-struck capital Z	U+1D551
			U+1D6A6	reserved
			U+1D6A7	reserved
			U+1D7CC	reserved
			U+1D7CD	reserved

Note: "Valid code point" should be allowed, these are older BMP characters. "Invalid code point" is where the new range contains a "hole" of unused / non-existing characters. These should NOT be accepted.

Uh oh!
