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 

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.
