I suppose "interprets the metrics" is a good summary. I don't
understand it completely.
The effect is, a font that is otherwise monospaced, and has the OS/2 monospaced
property, is displayed with letters of width that vary, unless the
is also set.
On Windows, a font will usually not be recognized as monospace, unless the
"isFixedPitch" flag is set.

Someone loudly and persistently disapproved. He produced one poor
argument after another,
(citing sources not easily available). I checked everything he
mentioned -- they all
appeared to support *my* case, not his. I'm still looking going
through a long discussion on
the private OpenType mailing list, to see if anybody has a solid
argument against setting this flag.
(The flag is mentioned, but this is not really what they were
discussing, near as I can tell.)

Well that's a thought, and I appreciate it. I don't think there's any
reason for Debian to
get involved to this degree at this point. (There have been flame
wars, as I said, and
you are likely to incur somebody's wrath by altering FontForge in this way.)
I was just informing you that there might be a problem: at the time, I
felt I had exhausted
all reasonable avenues -- but then I rememberd I'm a programmer.
The FontForge discussions are at
March and later this year.
A very messy discussion (starting with issues probably in PyGame, that
moved into discussion of new FreeType features, and then a re-has of
the FontForge question)
There were also some discusions on the closed OpenType list, that may

No, a program that sets the flag after FF builds it. I'm testing it now.
Good exercise anyway, maybe this code will be useful for other things.
