Question

I am trying to convert binary data to pdf417 barcode using pdf417bean class of barcode4J. But it is giving me following error

java.lang.IllegalArgumentException: Non-encodable character detected: Í (Unicode: 205)

Here’s a part of codebase I am using

        PDF417Bean bean = new PDF417Bean();

        bean.doQuietZone(true);
        bean.setModuleWidth(UnitConv.in2mm(moduleWidthInches));
        bean.setQuietZone(UnitConv.in2mm(quietZoneInches));
        bean.setBarHeight(height);

        boolean antiAlias = false;
        int orientation = 0;

        BitmapCanvasProvider canvas = new BitmapCanvasProvider(
                dpi, BufferedImage.TYPE_BYTE_BINARY, antiAlias, orientation);

        indiciaData = indiciaData.replaceAll("\\s+", "");
        byte[] binaryData = Base64.decodeBase64(indiciaData.getBytes());
        String base64DecodedMsg = StringUtils.newStringIso8859_1(binaryData);

        bean.generateBarcode(canvas, base64DecodedMsg);
        canvas.finish();


        String mime = MimeTypes.MIME_BMP;
        out = new ByteArrayOutputStream();

        final BitmapEncoder encoder = BitmapEncoderRegistry.getInstance(mime);
        encoder.encode(canvas.getBufferedImage(), out, mime, dpi);

I am using apache commons for conversion from base 64

Answer 1

I tried changing Barcode4J PDF417HighLevelEncoder class and changed encoding to ISO-8859-1 in place of Cp437. I generated a handful of barcodes and they are getting scanned correctly. Looks like it can be changed to support ISO 8859-1.
