i would hope that the consensus answer would be  'I', but alas i believe i
will be told something else.....

there are 2 different scenarios

a) case sensitivity for conditional processing possibly within test
conditions and predicates
b) case transformation for output

i'm interested in both, and i am certain that the Unicode effort is doing
case mappings;
http://www.unicode.org/unicode/reports/tr21/

i agree its hard, but the work is already being done by our use of Unicode.
