Well, that one actually has at least two reasons why it might work well:

 - RafaÅ sends his patches with an explicit "From:" line in the body
of the email itself (probably because he has had problems with email
headers in the past).  So his body itself has

    From: RafaÅ MiÅecki <rafal@xxxxxxxxxx>

 - Also, even ignoring that, he actually uses utf-8 in the headers
too, so his "From" header line looks like

    From:   =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= <zajec5@xxxxxxxxx>

so it is already in UTF-8, it just is rfc2047-encoded.

I suspect it's that first reason that patchwork.kernel.org gets it
right, but it *migth* be the fact that the problematic email is using
the old 'big5'  encoding:

    From:   =?big5?B?ufmxUrph?= <kt.liao@xxxxxxxxxx>

anyway, it does look like a newer version of patchwork will fix this.
