Using pseudo-MIME-encoding, that was actually (before my cut-and-paste
mangled it even more):

    Micha=c3=85=c2=82 Miros=c3=85=c2=82aw

And the correct utf-8 is

    Micha=C5=82 Miros=C5=82aw

and it *looks* like what happened is that something thought the input
was Latin1, and converted the Latin1 to UTF-8.

So the utf-8 character 'ł' (two bytes: =C5=82) was seen as two Latin1
character bytes: =c5 and =82.

And then each of those were converted mindlessly to utf-8, so the 'c5'
character became '=C3=85' and the '82' character became '=c2=82'.

So you have something that believes that a source file was latin1.

May I suggest just making absolutely *everything* on your system use a
utf-8 locale?

Because in this day and age, anything but utf-8 is just woefully
broken crud. "Just say no".
