As Aandi points out, one possible issue is the font data itself -
subsetting that not what you expect. You may also have other issues such
as the inter character spacing or the text matrix set elsewhere in the file.

That's pretty much the explanation. You may be able to find
information about 3x2 matrices elsewhere on the net - possibly in reference
to Postscript or SVG, since they all use the smae thing.
