Unicode and Mac keyboard layouts.

[Richmond]

Hey-Ho; there I am, merrily typing a letter to Mother in Sanskrit in
my (endless system development lifecycle) Devawriter and the Mac
merrily trips over into a Devanagari keyboard entry method that starts
interfering with the method in my stack . . .

. . . big, BIG, bummer!

1. Has anybody (err . . . Devin ?) had this sort of problem?

2. Has anybody any bright ideas how to overcome this?

sincerely, Richmond.
