[IronPython] Import decimal failure with Turkish Locale (IP 1.1)

This would have been my suggestion - this is a tough issue - do you have an expected behavior you'd like to see? I can imagine a few:
1. IronPython supports both byte-array strings and normal strings, and therefore "it just works"
2. IronPython never uses the current locale for string operations, effectively breaking Unicode
3. IronPython does a conversion into ASCII before doing attribute access, and somehow converts the upper case turkish I into an ASCII turkish I.
Those 3 options are problematic at best. An easier solution would be what Curt suggested (I'm assuming you're redistributing the standard library yourself). I was also thinking that there should be a preexisting way to do this in Python but I don't see an upper function that lets you specify the locale or force it to do so against an invariance culture. Maybe just a call to string.translate instead?

The issue is because one of the method names is '_round_ceiling'. In the
Turkish locale, the uppercase version of this is "ROUND_CEİLİNG" (in
Turkish uppercase of "i" is "I" with a dot on top of it). Obviously the
lookup of the corresponding global fails.
In CPython the name is a byte-string, and so '.upper' just uses the
ascii uppercase rather than the locale sensitive version - so we see
failing to import 'decimal.py' as an IronPython bug. As this badly
impacts Resolver we would *love* to see this fixed soon...
Why not change decimal.py to use ToUpperInvariant()? Are you sharing the file with CPython?
