I probably did not make myself clear. I want to use the "Charis SIL" font (actually, another font that I intend to purchase, but let's keep things simple) for my regular text, bold, and small caps, but the font specified by mathdesign for italic and bold italic. These fonts are provided in my MikTeX installation, in the folders

fonts\type1\bitstrea\charter\bchri8a.pfb

and

fonts\tfm\bitstrea\charter\bchri7t.tfm (and several other .tfm files, with last two characters 8c, 8r, 8t).

I do not know how to specify this font to ItalicFont. The following code in my document:

 \usepackage[no-math]{fontspec}
 \usepackage{xunicode}
 \usepackage{xltxtra}
\usepackage[bitstream-charter]{mathdesign}
\setmainfont[ItalicFont={bchri}]{Charis SIL}

Gives the following error message:

lled font not found.

(and a hundred more of similar lines)

If I replace "bchri" in that code by "Comic Sans MS" then everything works as expected.

By the way, thanks a lot for the time you've already taken to reply, and most of all for the development you've done: with XeLaTeX the future of maths typesetting looks bright!

Kind regards,

Stefan.
