/// This encoding roughly matches the Windows code page 28597. Windows decodes
/// unassigned code points, the currency signs at 0xA4 and 0xA5 as well as
/// 0xAA, which should be U+037A GREEK YPOGEGRAMMENI, to the Private Use Area
/// of Unicode. Windows decodes 0xA1 to U+02BD MODIFIER LETTER REVERSED COMMA
/// instead of U+2018 LEFT SINGLE QUOTATION MARK and 0xA2 to U+02BC MODIFIER
/// LETTER APOSTROPHE instead of U+2019 RIGHT SINGLE QUOTATION MARK.
