Patchwork modifies 'From' field

[Brian Norris]

Does Patchwork ever change the name in the 'From' field of a patch?
Perhaps based on prior knowledge of a person's name?

I see that Ezequiel Garcia's last name is spelled "García" (with an
accent mark) under "Submitter" on patches like this one:

http://patchwork.ozlabs.org/patch/391517/

And the mbox linked from patchwork shows the accent in the From
header. But the raw mail in my account shows that his original mail
had no accent mark.

How can I fix this? I don't want to pull patches from Patchwork and
only realize later the metadata is all wrong. I would really expect
Patchwork not to muck with things like names, but if it has to, I'd
hope there's a way to get around it. Can a user register an account
under their email address and change their name, for instance?

Thanks,
Brian
