Hi, everybody!

   When I generate patches using "git format-patch" it always makes
my name garbled in the "From:" line
as shown below. I'm using openSUSE 11.2 RC 1 (x86_64) with the
following settings:

       # locale charmap
       UTF-8
       # echo $LANG
       en_US.UTF-8

   I've tried changing my environment to use another encoding like
ISO-8859-1, but it didn't work as well.

   Does someone can explain why does this happens? Any suggestions?

P.s.: the problem never occurs on the commit message (Signed-off-by)

This is the normal encoding for email headers where you cannot use
8bit characters. You have to use a 7bit characters with this
=?UTF-8... encoding.

You can check the From: line in your mail, the mail I'm replying:

From:	=?ISO-8859-1?Q?Andr=E9_Goddard_Rosa?= <redacted>

At the other hand the tools using the output of git-format-patch must
deal with this all, as they do. git-am handles it well, if not it's a
bug that should be reported.

Great, Santi!

     I really appreciate your reply!!!

    I was just in the process of debugging this issue when I landed
into function pp_user_info(), which calls add_rfc2047(). So I started
looking into http://www.faqs.org/rfcs/rfc2047.html , which specifies:

"Generally, an "encoded-word" is a sequence of printable ASCII
characters that begins with "=?", ends with "?=", and has two "?"s in
between."

Ok... I got it; it's necessary for proper signaling of the email
header when it detects the presence of certain characters outside the
ASCII range 0..127 (7 bits). It's the case for latin "é" letter in my
name.

So, let me explain what happened to me:

I'm not using any specific tool for inputting the git-format-patch,
but instead I'm sending the files generated by it through gmail as an
inlined patch in the email body.

I like the convenience of format-patch for generating the patch files,
but in this case, formatting the header as rfc2047 is not necessary
and makes a funny/garbled output in my patch submission.

Do you have a suggestion for my workflow?

Thanks a lot,
André
