Being one of the few people that actually uses native PostScript around
here gets me in trouble on occasion.  This is one of those times.

I've been asked if I would find a way to replace four characters--the
yen sign (0xA5), the florins sign (0xA6), the section sign (0xA7), and
the "splat" sign (0xA8)--with the upper- and lowercase thorn, and the
upper- and lowercase yogh, respectively.  (These are generally used in
Old English texts, and look vaguely like "P"s, incidentally.)

My problem is that I'm quite used to drawing figures, but haven't a
clue as to go about working on fonts.  I assume lineto and curveto
operators would be on the slow side, but I don't know how else to go
about it.  Plus I haven't the faintest idea how to tell PostScript
to use my routine instead of the yen-sign routine when it hits a
0xA5 code.

Could someone out there get me started?  Of course, if there's a
thorn and yogh set out there, that would be delightful.  But if
not, I need some serious help. . . .

Thanks. . . .
