Barcode4J pdf417 module is giving error

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

The inputData indiciaData is a base64 encoded binary data. Here's a similar bug from Barcode4J bug base sourceforge.net/tracker/…. Not sure if This is a similar scenario. — Arpit Gautam

You need to use new String(binaryData, "Cp437") instead of ISO-8859-1. The page on PDF417 says to use that encoding. Other encodings are not currently possible. Unfortunately, the "Í" is not in Cp437 so can't be used. If you download Barcode4J from CVS HEAD and compile it yourself, you can use RFC 2397 data URLs to use binary data: PDF417 description for development version.
