Aye, this made the implementation far more messy than it could have been.
Unicode-math has quite a number of exceptions hard-coded with their own c=
snames, such as:

\usv_set:nnn {bb}{C}{"2102}
\usv_set:nnn {bb}{H}{"210D}
\usv_set:nnn {bb}{N}{"2115}
\usv_set:nnn {bb}{P}{"2119}
\usv_set:nnn {bb}{Q}{"211A}
\usv_set:nnn {bb}{R}{"211D}
\usv_set:nnn {bb}{Z}{=932124}

The vargreek symbols in particular are in inconsistent locations, but the=
re=92s only a few of them so it=92s not the end of the world.

Cheers,
Will
