   Thanks, I never would have found that one!

I tried to highlight it as much as possible:-)
See the yellow blob in :

http://www.w3.org/TR/MathML2/italic.html

which is linked from chapter 6 of the spec.

  I find that an interesting justification for the lack of an assignment for
  "MATHEMATICAL ITALIC SMALL H", as wouldn't this character actually have
  different semantics to "PLANCK CONSTANT"?


The Math WG argued that the existing BMP characters should be defined to
have "specific" semantics, and the new ones should be defined to be
generic alphabetic runs. If Unicode really is a semantic character set
rather than a glyph collection this would seem reasonable. But the UTC
decided against this.

In this case (planck) they may well have agreed, but in others such as 
double struck C
2102 DOUBLE-STRUCK CAPITAL C
they probably had (a bit) more reason to refuse to classify this as "the
complex numbers" and allow 1D39A as a generic double strck C.
