support for block 1D400--1D7FF

[Luca Padovani <lpadovan cs unibo it>]

Hi,

the block range mentioned in the subject contains Mathematical
Alphanumeric Symbols. Althought they are meant to be used for
mathematics, these can be considered as just font variants for latin and
greek letters, and the digits from 0 to 9. For example, U+1D434 is
MATHEMATICAL ITALIC CAPITAL A. Is there any plan to include support for
these chars in Pango? Or is there any way of "configuring" pango so that
it maps these characters like a <font-style,plain char> combination?

TIA,
