commitEncoding is equal to filenames' encoding, Windows-1251, of course.

Well, despite `git log --help` 
           The raw format shows the entire commit exactly as stored in
           the commit object"
on a Linux box (UTF-8) I can see "readable" commit messages nevertheless
they are stored in 'Windows-1251' (so they are converted to UTF-8). To
be sure I've checked actual content of them with `git cat-file commit`
Actually, to be honest, I usually use modified version of Git (see
ecaee8050cec23eb4cf082512e907e3e52c20b57) in 'next' branch, that could
affect the results, so I've checked `git log --format=raw` with
unmodified v1.8.3.3 of Git.

But let's go back to the answer to your question. Commit encoding stored
as a header in a raw commit messages is 'Windows-1251'.

This is a "closed" (commercial) project and every developer uses Cygwin,
except me. I use a Linux box as a desktop (mail, IM, web-browsing; but
development goes on Cygwin). And sometimes I run utility scripts
included to that project on my desktop (as far as Linux works with files
much faster than Cygwin does ;))
Also, a Git server is a coLinux box (http://www.colinux.org/) on a
Windows Server 2003, but I guess, it does not much matter here.

Yep, one of our developers tried to use modern version of TortoiseGit
with MinGW port of Git. That was a failure. As far as since v1.7.9 MinGW
port transcodes filenames to store them internally in UTF-8. This
problem could be solved with converting once that non-ASCII filenames to
UTF-8, but I do not want to use MinGW port. I like Cygwin
"infrastructure" that is more Linux-like than MinGW.

I'd be happy if such a setting exists. That could solve many problems
with cross-platform projects with non-ASCII filenames.
Indeed, MinGW port does resolve that problem somehow!
