Hi Clea, Peter and others,

Firstly, sorry for the cross-posting.
We want to move this discussion to the XeTeX list.

As in the attached image?
I get it too, with Regular only. Bold and Italic seem OK.

Yes, only some fonts are bad.
I'd doubt that this is a caching problem --- but am willing
to stand corrected, should it turn out to be so.

Would you show exactly the command which worked, please?

I can show you how to replace the missing characters with accents
built as with older LaTeX styles, but while still using proper
accented characters for those which *are* in the font.

  ... and not redefining accent-macros for other fonts in the same
document which may actually support everything properly.
It's a bit more cumbersome than it should be, but it *does* work.

In the image, you'll see that \^W \^Y etc. use this.
There is a bit of a glitch in that the accents are placed a tiny
bit higher than those over the pre-built characters.
So there needs to be an extra font-specific vertical adjustment.
