OK, so that means WildWezyr isn't just seeing things. Possibilities
that occur to me now:
1. Maybe it's specific to Vista and/or Win64?
2. I wonder whether setting LC_COLLATE/LC_CTYPE during database creation
is really sufficient to establish the locale fully on Windows. If
wcscoll() is partially dependent on some other bit of state, maybe that
would explain the problem. What is the "surrounding" locale in your
test case?
