Why are some QR Codes containing diacritic incorrectly decoded?
This problem is caused by incorrectly created QR Codes that use QR Code Kanji (Shift JIS X 0208) encoding. Use this code for decoding:

function DecodeQRCode(Data: TBytes): string;
var
  Utf8: string;
  ShiftJIS: TBytes;
begin
  Utf8 := TEncoding.UTF8.GetString(Data);
  ShiftJIS := TEncoding.GetEncoding(932 {Shift JIS }).GetBytes(Utf8);
  Result := TEncoding.ANSI.GetString(ShiftJIS);
end;
