Not sure where I'd find the meta header, but at the top of the HTML:

<!-- git web interface version 1.4.5-rc0.GIT-dirty, (C) 2005-2006, Kay
Sievers <kay.sievers@xxxxxxxx>, Christian Gierke -->
<!-- git core binaries version 1.6.1.1 -->

Dug around gitweb.perl in the main git repo. Then looked at the
git/warthog9/gitweb.git repo (after noting the Git Wiki says kernel.org
is running John Hawley's branch).

One notable change to git_blob_plain:

        undef $/;
        binmode STDOUT, ':raw';
-        print <$fd>;
+        #print <$fd>;
+        $output .= <$fd>;
        binmode STDOUT, ':utf8'; # as set at the beginning of gitweb.cgi
        $/ = "\n";

        close $fd;
+
+        return $output;

If that's the code that's running, doesn't that mean the output mode
change doesn't impact the concatenation to $output? So the blob gets utf
encoding when actually printed.


Regards,

Dave.
