ISO-8859-2 and Windows-1250 are absolutely similar for all letters in
the Hungarian alphabet. So for most texts, it is not an error to return
one charset or the other.
What could make the difference is for instance that Windows-1250 has
some symbols where ISO-8859-2 has control characters, like quotes,
dashes, the euro symbol…
Since control characters have a negative impact on confidence now,
texts with such symbols would tend towards Windows-1250 decision.
The new test file has such quote symbols.
