X11R6 comes with a unifont.pcf.gz (size 814081 bytes; it must have
been released not later than than 2003-Feb-04) which works fine with
the ftview demo program on my Linux box.  Please download it and check
whether this version works OK for you too.  [

My suggestion is to try your font with the ftview demo program.  If
that fails please send an URL where I can download the font for
further investigation (even better would be a font reduced in size
which you can send me directly).

I also get a pitch of 4 for my version of unifont.pcf.gz, so this
shouldn't be a problem.
