I need to substitute the regular and italic characters of a
publisher’s non-math font (Unicode) for those in a math font.
The non-math addresses are:
0041-005A, 0061-007A %italic uppercase and lowercase
0391-03A9, 03B1-03C9 %slanted Greek uppercase and lowercase
The math addresses are:
1D434-1D44D, 1D44E-1D467 %italic uppercase and lowercase
1D6E2-1D6FA, 1D6FC-1D714 %slanted Greek uppercase and lowercase
Is there a way to use the \definefallbackfamily mechanism that does
not assume that the characters have the same Unicode addresses? Or is
some other approach required?
The fallback mechanism provides a offset key which lets you replace a
math character with a normal text character.
