    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.
