AFM is what I meant by "metrics file".

Shouldn't the AFM file contain the values for Ascender, Descender, XHeight &
CapHeight?

In the case of Latin fonts  these values are usually pretty easy to derive anyway.

Stems and alignment zones are also in the font files

*If* they traced the outlines in Fontographer.

Since Adobe were making only PostScript fonts - I doubt if there would be
diagonal hints.

There is a good chance Adobe developed Utopia using something other than
Fontographer anyway.

The  point was that in the case of Type 1 fonts there may be little or
no useful extra information contained in the Fontographer "source" file.
Anyway the font files themselves are probably readable by many more
applications that the Fontographer files.

Something like the designers original sketches for the font might be
far more useful to anyone wanting to extend a font like Utopia ...
