Description mitz 2011-12-30 12:21:35 PST
To reproduce, compare <https://bugs.webkit.org/attachment.cgi?id=120812&action=prettypatch> to <https://bugs.webkit.org/attachment.cgi?id=120812>. Notice that every apostrophe in the latter appears as â in the former.

The plain diff is encoded as and served as UTF-8, with the apostrophe encoded as E2 80 99. In the formatted diff, each on of those bytes appears to have been interpreted as Latin-1 and then encoded as UTF-8, resulting in the sequence C3 A2 C2 80 C2 99.

attachment.cgi sub prettyPatch:

>    $ENV{'PATH'} = $orig_path;

I guess OUT works as binary, and "print" converts a binary line to UTF-8 because of binmode.
Probably utf8::decode($_); before print fixes this?
