[Groff] PostScript question

[Peter Schaffter]

Hi.

I had someone write me saying that when they processed a mom
file with groff 1.18.1 for PostScript output, the letters ACEI
(both upper and lower) were coming out as ] (i.e. as right square
brackets).

Here's the sample mom file:

.GREETING 
Hi Peter
.PP
Here is an example of a letter using groff and mom. The next sentense contains
the letters of the alphabet in lowercase. abcdefghijklmnopqrstuvwxyz. 
Here they are again in upper case. ABCDEFGHIJKLMNOPQRSTUVWXYZ. 
Thank you, and have a nice day.
.CLOSING
Sincerely,

He sent me the .ps file as well, which ends this way:

When I processed his mom file, the corresponding part of the
resultant .ps file looked like this:

====================================================================

Can someone explain why the .ps file sent to me has the text
in code, while the file I generated shows the text as text?  And
why ACEI are coming out as brackets?  Is it a font problem, a gs
problem, or a grops problem?

Thanks.
