Does anyone know Postscript well enough to help track down an apparent
bug with the OS/2 driver?

I have a DeScribe document with a graphic that contains a text element
with the name Schonberg.  It prints just fine under some circumstances,
namely combination of font and attributes.  I'm using HelmetCondensed
and bold.  If I change the o to o-dieresis, it still displays and
prints properly, until I change one of the attributes to hollow, after
which it displays properly, but prints as something that looks like
Courier.  The same problem occurs with Helvetica Narrow, Swiss, and a
few other fonts that I tried, but it printed properly with @Lucida Sans.

I've looked at the Postscript, but there's nothing obviously wrong, at
least to someone who doesn't know low-level Postscript.  I tried a few
things by editing the Postscript and letting Ghostscript show me what
happens as a result.  For example, I found a single occurrence of a
Font1001 string whereas the other places where it appears, it said
only Font100, so I tried changing the 1001 to 100, but that didn't
fix it.  Not knowing Postscript is like stumbling around trying to
find your way in the dark.

The main difference after changing the o to o-dieresis is that the
character shows up in the Postscript as \224, which is the octal code
for the character, and before that code appears in the Postscript, a
lookup table for all 256 characters in code page 850 is inserted,
with o-dieresis appearing as character 148 (= 224 octal).  So that
part seems to be correct.

If it can print o-dieresis properly without the hollow attribute,
shouldn't it also be able to print it with the hollow attribute?
