It''s likely that some glyph in the font is wider than expected and
pushes
all of the other glyphs out a bit; Xft enforces the monospace attribute by 
setting all of the glyph advance values to the maximum advertised in the 
font when directed to use monospaced fonts by an application.  Firefox 
doesn''t request monospacing, so the font isn''t adjusted in
that
environment.

Note that the .pcf.gz fonts which work fine for me do not exhibit this 
problem; it may be an issue with the OpenType transformation application.

This problem is puzzling:

I have an OpenType font with embedded bitmaps. The font is a monospace
font that I use for coding and for my terminal windows.
It is in OpenType/Bitmap format, because I am unable to get my gnome-based
applications to work with either the PCF, BDF or FON version of this font
(see my previous email about that).
The problem is that when I use the font in a gnome-based application, such
as gnome-terminal, or KDE application like konsole, the glyphs have an
extra single pixel inserted between them, so the spacing is too wide. For
instance, two underscore characters (__), will be displayed with a
one-pixel gap between them.
However, freetype shows the font correctly (using ''ftview''),
and some
applications have no trouble with the font: FireFox is configured to use
this font for monospace text, and it shows it perfectly, without the extra
spacing.

Any idea why this would be ?

(I''m attaching two small portions of screen capture to show the
problem)
