- This may seem like an esoteric problem, but it's very real when you

- For a book I'm doing, I need to use PostScript versions of the CM fonts;
- bitmapped versions are unacceptable. Fortunately, Blue Sky Research
- sells Type 1 versions of the CM fonts, 75 in all. I've bought them and
- installed them. Everything seemed to go smoothly until I tried printing
- the quadratic equation. That is, I used the simple Plain TeX expression:
-
- $$-b\pm\sqrt{b^2-4ac}\over 2a$$
-
- Curiously, all elements appeared to be correct, except the minus and
- plusminus signs were missing. I've tried several other equations with
- integral signs, matrix brackets, greek characters, etc., and I get
- mixed results. For example, theta is missing, while alpha and phi are
- correct. Also, the multiply "x" and left arrow don't appear. Any
- thoughts on what might be amiss? Seems like an encoding problem, but
- I wouldn't know where to look. Since this problem is not likely to be
- of widespread interest, please reply directly to me at rlp@lanl.gov.

- Sounds like you may have used an inappropriate tool for converting the fonts
- to a format suitable for the NeXT. What did you use to do this? Did you
- start with the Mac or the PC version of the fonts?
-
- Note that many conversion tools are not suitable for fonts other than plain
- vanilla text fonts. They have trouble with fonts that do not use the usual
- encoding, particularly if the font uses characters in the 0 - 31 and range
- (and 127), or if the font does not have a space in 32.
- Are the characters you are missing in the 0 - 31 range?
-
- What version of DVIPS are you running? Some older versions had a problem
- with fonts that use repeated encoding (if not reflected in the TFM file).
-
- Also, Display PostScript is rather fussy about what is in the AFM files.
- Most applications don't look at AFM files, so what exactly is in them is
- of little concern, but Display PostScript does care.
- For example, it may group fonts based on FamilyName, which is the same for
- all 75 of the CM fonts
-
- Life is a bit easier if you buy fonts already set up for Display PostScript
- on the NeXT...
