git log and utf-u in filenames

Git, particularly git-log seems to not display utf-8 characters in filenames,
instead showing an escaped representation. On the other hand, commit messages,
as git-log(1) notes, are assumed to be utf-8, and the same utf-8 character
used in a commit message is not escaped, and displays ok.

Can anyone point me at the documentation for this utf-8 filename escaping,
assuming it's not a bug? And did earlier versions of git (circa 2006) perhaps
not do that escaping? I have code in ikiwiki that apparently used to work, but
is certianly not working with current git, due to this escaping.

Here's an example of the inconsistent handling of the same utf-8 character
("ö") in commit messages and filenames.
