I'm cleaning up some data which has text description fields from

A few more cases:
bytearray(b'\xe5\x81ukasz zmywaczyk')
This one has to be Polish, and the first character should be the
letter Ł U+0141 or ł U+0142. In UTF-8, U+0141 becomes C5 81, which is
very similar to the E5 81 that you have.
So here's an insane theory: something attempted to lower-case the byte
stream as if it were ASCII. If you ignore the high bit, 0xC5 looks
like 0x45 or "E", which lower-cases by having 32 added to it, yielding
0xE5. Reversing this transformation yields sane data for several of
your strings - they then decode as UTF-8:
miguel Ángel santos
I think that's:
miguel ángel santos
lidija kmetič
Łukasz zmywaczyk
jiří urbančík
Ľubomír mičko
petr urbančík
That doesn't work for everything, though. The 0x81 0x81 and 0x9d ones
are still a puzzle.
