substituting characters in math font

substituting characters in math font

[Alan Bowen]

[-- Attachment #1.1: Type: text/plain, Size: 605 bytes --]

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?

I am resending this in the hope that some font will find him/herself with
time to consider an odd query.

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

The fallback mechanism provides a offset key which lets you replace a 
math character with a normal text character.

Many thanks for this, Wolfgang. That is very helpful. Right now, then, I
have:

As you can see, all I need is to get the Brill lowercase Greek in mathmode
and the proper slanted Greek theta. I have tried this with Pagella and
Cambria instead of the Brill font and the problem persists. So I must be
doing something wrong. But what?

The font name for the third argument is *always* Brill and not 
BrillItalic or BrillBold.

Pagella and Cambria have a proper math font, why would you use fallbacks 
for them.

Re: substituting characters in math font

[Alan Bowen]

[-- Attachment #1.1: Type: text/plain, Size: 3332 bytes --]

OK—that makes sense, since Brill is the family name. But then changing
“BrillItalic” to “Brill” will not get the italic math characters (Roman or
Greek). So, is there a way to get these italics using \definefallbackfamily
or must one use \definefontfallback (as Hraban and I eventually did)?

I was using Pagella and Cambria to convince myself that the problem was one
in my encoding and not some problem with the Brill font.

Best, Alan
