[lucida] lucida-amsmath.tex for Lucida OpenType fonts?

[John H Lienhard]

Thank you, Bruno.

The code you sent, and also the file from Herbert Voss, both work very conveniently for immediate use under XeTeX using some other math code.

However I also get the error you mention using these approaches on lucida-amsmath.tex under XeLaTeX:

        ! Internal error: bad native font flag in `map_char_to_glyph’

The error goes away when I remove "\wh” from the following line of the file:

        \wh{\mathbf{K}}(i|i),\qquad i=1,\dots,n.

( \wh is shorthand for \widehat in the lucida-amsmath code: \newcommand{\wh}{\widehat}.)

This is under the most recent release of the OT fonts and of Texlive. Of course, I have no idea why this error occurs!

But you have resolved fully my more immediate question.

        Thanks again,
        John

PS: I’m attaching the modified file; the problematic line is 173. Everything else works works fine.
