Yeah, I wonder if this is a symptom of a deeper issue, which is that utf-8 has many synonyms, and we would prefer to canonicalize the encoding name before generating an object to avoid inconsistencies (of course we cannot do so for every imaginable encoding, but utf-8 is a pretty obvious one we handle already). We _should_ be generating commits with no encoding header at all for utf-8, though. And indeed, it looks like that is the case. commit_tree_extended has: /* Not having i18n.commitencoding is the same as having utf-8 */ encoding_is_utf8 = is_encoding_utf8(git_commit_encoding); [...] if (!encoding_is_utf8) strbuf_addf(&buffer, "encoding %s\n", git_commit_encoding); which makes me think that this first hunk... > diff --git a/t/t4210-log-i18n.sh b/t/t4210-log-i18n.sh > index 52a7472..b1956e2 100755 > --- a/t/t4210-log-i18n.sh > +++ b/t/t4210-log-i18n.sh > @@ -15,7 +15,7 @@ test_expect_success 'create commits in different encodings' ' > t${utf8_e}st > EOF > git add msg && > - git -c i18n.commitencoding=utf8 commit -F msg && > + git -c i18n.commitencoding=UTF-8 commit -F msg && > cat >msg <<-EOF && > latin1 ...should be a no-op; the utf8 there should never be seen by anybody but git.

It's a larger change, but I think it makes git friendlier all around for people on Windows. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
