@akurakkauaaa: great piece of code!
The text is encoded in ISO8859-2. If you want, you can use the following function to get the text in ANSI (works only for Polish):
Func ISOtoANSI($sText)
; http://en.wikipedia.org/wiki/Polish_code_pages
$sText = StringReplace($sText, Chr(Dec("A1")), "Ą")
$sText = StringReplace($sText, Chr(Dec("A6")), "Ś")
$sText = StringReplace($sText, Chr(Dec("AC")), "Ź")
$sText = StringReplace($sText, Chr(Dec("B1")), "ą")
$sText = StringReplace($sText, Chr(Dec("B6")), "ś")
$sText = StringReplace($sText, Chr(Dec("BC")), "ź")
Return $sText
EndFunc ;==>ISOtoANSI
