Hmm... That's a bit misleading - it *claims* that the Unicode characters that
I'm interested in are included in the DejaVu fonts, which I had already
installed, but I don't see these glyphs.

I had already installed the first two, and I now have installed the last
(which had seemed promising), but to no avail.

Yep - I like them too.

Thank you - I didn't know that.

As it *appears* that the font packages provided by Cygwin setup do not
provide the glyphs I need, and since I already knew that the DoulosSIL
package worked under FreeBSD, I went to the Doulos site and downloaded the
font package from there.  I first copied over the .ttf file to the Windows
font directory, without apparent effect.  But, I cannot say how delighted I
was to find that after copying the .ttf file to the Cygwin fonts directory,
that Cygwin Emacs displayed the characters correctly!

So, although the process was not as straightforward as I might have liked, I
now have a working solution due to your very helpful information.  Thank you.
