[Referring to
http://lists.gnu.org/archive/html/bug-groff/2011-02/msg00007.html:
In my recent attempts to use groff 1.20.1 and the lj4 post
processor, I have encountered a number of instances where certain
character pairs (ff, fi, fl, ') are passed on to the hp printer as
escape sequences that print as (1/2,¡,«, Æ). I discovered that (ff,
fi, fl) are actually transferred to the printer as escape sequences,
(\xab, \xad, \xae) and suspect a similar code for '. This leads me
to believe that the lp4 post processor may have a problem. Can
someone explore this and provide a solution?]
Hi Jeff!
Great to hear from you again! I take the liberty to CC the groff
mailing list so that the discussion gets properly archived.

No. There was a fundamental change under the hood how glyphs are
represented, but theoretically this shouldn't affect grolj4.

Thanks for this information.

He's listening :-)
