Minion Pro Italic is exceptionally weird regarding identifiers in
that the postscript fontname and both info.fontname and
info.fullname are given as “minionproit”. Now its english fullname
(field 18) is “minionproital”. Only the value “fullname” in the root of
the tfmdata structure (not the one returned by fontloader.info()!)
accurately yields “Minion Pro Italic”.
To complete the picture, the file naming isn’t very consistent either:
we find the suffixes “Regular” and “Bold”, but “It” and “BoldIt”. What
the hell were the designers smoking?
Also, the full Minion Pro set comes with different optical sizes which
for monetary reasons cannot considered here.
