Thanks for clarifying.  So in the context you describe, (1) is
configurable, (2) is Windows-1251, (3) is unconfigurably UTF-8, and
there is no way with current git facilities to force the email to use
a single encoding unless (3) happens to contain no special characters.

What is the value of the "[i18n] commitEncoding" setting in your
project?  What encoding do the raw commit messages (shown with
"git log --format=raw") use for their text, and what do they declare
with an in-commit 'encoding' header, if any?

Does everyone on this project use Cygwin?  That should be fine, but
I'd expect there to be problems as soon as someone wants to try the
Mingw port ("Git for Windows").

I wonder if there should be an "[i18n] repositoryPathEncoding"
configuration item to support this kind of repository.  Then git could
be aware of the intended encoding of paths, could recode them for
display to a terminal, and at least on Linux and Mingw could recode
them for use in filenames on disk.  "repositoryPathEncoding = none"
would mean the current behavior of treating paths as raw sequences of
bytes.

What do you think?
