Hi Werner,
there are a few funny things indeed.  The font "Nimbus Mono L Regular"
(Courier), for instance, sets "/isFixedPitch false def".  This is
strange.  However, it's not a bug.  According to the Type1 specs, the
whole /FontInfo dictionary is optional and doesn't have to exist at
all.

Thus any software which relies on it is faulty.  Ghostscript, for
instance, doesn't rely on /isFixedPitch at all and compares the widths
of the glyphs in a font in order to decide whether it's monospaced.

Neither TeX nor any PostScript interpreter depends on these entries.
They are part of the /FontInfo dictionary and thus don't have to
exist at all. 

On the other hand, all fonts I've seen have these entries and it's
compelling to make use of them.  But if programs rely on conventions
(Condensed Regular instead of Regular Condensed), it's better to
modify the programs rather than the fonts.

Since all programs are using fontconfig nowadays, couldn't fontconfig
provide aliases?  I'm not familiar with fontconfig at all but hasn't
it been invented in order to solve such problems in the first place?

Modifying fonts is definitely the worst thing we can do for obvious
reasons. 

Regards,
  Reinhard
