I still don't understand why this would work...  upper half of what?
I'd assume "upper-half" refers to characters in the 16#A0#..16#FF#
range, but the original poster had problems when it processed a Greek
"pi" in a runtime source, which isn't in the upper half of anything
(unless you count ISO-8859-7, the Greek alphabet!).  It's certainly
not anywhere in Latin-1 (ISO-8859-1).  And I doubt that "upper-half"
means the upper half of Unicode (16#8000#..16#FFFD#?), which I believe
would start somewhere in the middle of the Chinese character set.  So
why would -gnatif magically make pi work?  Mighty strange.........
