Because gamma, not chi, is the third letter of the Greek alphabet?

yes, but gamma is 947, and chi is 967, so _why_ is c mapped to chi and
not gamma?!

Ask Adobe, they defined it.

I guess their Latin/Greek mapping is like KOI8 based on some
phonetic/graphic similarities between Latin/Cyrillic letters.
Someone who sees KOI8 for the first time might wonder and ask
exactly the same question why the order is not alphabetical ;-)

Hint #1: what is g mapped to?
Hint #2: you _are_ aware that historically, c and g was the same letter?

Because they preferred to map g to gamma?  c doesn't have a direct
correlate, so they put it on something that's not entirely unreasonable
(given its English spelling): chi.

The input method `greek' maps g to gamma too, though it takes the other
sound for c and makes it psi and makes x chi (and j xi).

The mapping is that of the Postscript font /Symbol's encoding.  Clearly
either Adobe or Apple wanted a phonetic mapping, presumably so that
keyboard entry would be intuitive for the Mac's (initial) market.

Remember also that the /Symbol font had Greek not for setting Greek text
but rather for setting Math and the like.
