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:
Add this line before scaning barcode:
Obr.Configure(syQrCode, saNone, coEnableSymbology, 0); // disable QR code symbology
How can I enable recognition of some symbology?
Add this line before scaning barcode:
Obr.Configure(syQrCode, saNone, coEnableSymbology, 1); // enable QR code symbology
How can I scan UPC/EAN barcodes with 5 digit extension?
Add this line before scaning barcode:
Obr.Configure(syEan5, saNone, coEnableSymbology, 1);
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;
