It seems to me that that's too narrow a definition of the problem.
I think we should state our goal as "we don't want bizarre locale
definitions to interfere with downcasing of the basic ASCII letters".
If we put in a special case for 'I' we will fix the known problem
with Turkish, but what other strange locales might be out there?
And if we don't trust tolower() for 'I', why should we trust it
for 'A'-'Z'?
What it comes down to is that by training and experience, I always
expect that any bug might be just one example of a whole class of bugs.
You have to look for the related cases that might happen in future,
not only fix the case that's under your nose.
