Ok. Probably what has happened is you have committed two files to the
repository whose names contain the same UTF-8 characters but in one
case the characters are represented in composed form and in the other
case they are represented in decomposed form. Linux and Windows by
default create names in composed form, while Mac OS X creates names
in decomposed form. Linux and Windows will happily use files of
either representation. If you have both in your repository, they will
have no problem checking this out and showing you two different files
that appear to have the same name. Pretty confusing. Mac OS X will
attempt to convert both of these to the same (decomposed)
representation, but fail on the second one because the file of the
same name already exists.
You can use "svn ls" on the URL of the directory in question to
verify this. You should then use "svn cat" on the two files to
determine which one you want to keep, and "svn rm" the other one.

Ok. Then there is nothing wrong (nothing corrupted, anyway) in your
repository.

Well there's probably no harm in setting the variable yourself
instead of having Terminal do it for you automatically.

I haven't used SmartSVN. I cannot explain why it would not suffer
from the problem.

What would you have your pre-commit hook do? The only workable thing
I could think to have it do would be to only accept filenames in
decomposed UTF-8 representation and deny filenames in composed UTF-8
representation. This would mean anytime you want to create a new file
with UTF-8 characters, you would have to do so from a Mac (since
that's the only platform that creates decomposed UTF-8 filenames).
And that's probably inconvenient for your non-Mac-using coworkers.
