The interactive rebase command builds a text file and passes it to
editor specified as environment variable or as configuration
parameter. However the man page for rebase operation says nothing
about which encoding will be used for that file. Apparently
i18n.logoutputencoding is used. I think that the man page for rebase
operation should explicitly specify it.

Also it might make sense to use explicit encoding parameter for
interactive rebase operation.

Care to send a patch?

Do you have a use-case where having a different encoding for log output
and rebase -i todo list makes sense?

Thanks.

As rebase -i does nothing else than piping the output of git log into a 
file (at least this is the first step), I thought it would be obvious that 
it uses the output encoding preferred by the user.

Indeed, I cannot think of any scenario where it might make sense to have a 
different encoding in git rebase -i than in git log.

Yes. That was my first hypothesis, but I had to check it through small
experiment and source code examination. And if consider the bug
described in the thread
http://kerneltrap.org/mailarchive/git/2008/11/11/4063184, the
hypothesis might have been incorrect.

For IDE, it might make sense to force UTF-8 encoding instead of using
currently configured logoutputencoding. Currently the extra call to
git config is needed to check expected encoding of the file before
data could be shown to the user. Also user specified encoding might
fail to display some characters in commit messages that was encoded
using other encodings, forcing UTF-8 would have also fixed this
problem as well.

BTW for IDEs an option that causes non-abbreviated commit hashes would
have been useful as well.

I consider rebase -i to be porcelain, and as such not suitable to be used 
as a backend for an IDE.  Help the git-sequencer effort if you want a 
plumbing.
