When using code128 in particular, several letters overlap. Most
prominently, upper-case M and W, but also others. They are very wide
and not being given the extra room they need. e.g. barcode -e code128
-b MWMW0M00W01
I can increase the margin, but that doesn't look very good and wastes a
lot of space all the time, just to catch the few worst-cases. My simple
fix is to undo to the change to Helevtica (see ChangeLog), which has
variable width characters, and go back to fixed-width CourierBold. It
works nicely here.
