Does LiveCycle Digital Signatures support unicode pkcs #12 file?

Question

I used Adobe Acrobat and OpenSSL to generated a unicode pkcs#12 file. Import to the Windows are all correct. But when I used for LiveCycle Digital Signatures, after signed, the one use Acrobat generated pkcs12 file signed only can show ASCII character，and other one used OpenSSL pkcs12 file to signed,signature character changed to  irrecognizable.

Answer 1

These are two unicode pkcs #12 files. one created by openssl, another one created by Acrobat.
I used this code to sign to the PDF file.
        try    {
            // This example will upload an XDP file to the LiveCycle Repository
            ServiceClientFactory myFactory = ServiceClientFactory.createInstance(LCCommonUtil.getConnectionProps());
            // Create a SignatureServiceClient object
            SignatureServiceClient signClient = new SignatureServiceClient(myFactory);
            // Specify a PDF document to sign
            FileInputStream fileInputStream = new FileInputStream(
                    "C:\\Applications\\pdfForms\\TestDigitalSign\\ConferenceReg_flatten_sf_added.pdf");
            Document credDoc = new Document(fileInputStream);
            // Specify the name of the signature field
            String fieldName = "SignatureField1";
            // Create a Credential object
            Credential myCred = Credential.getInstance("BLC_CHINA"); // LC Server: Local Credentials
             System.out.println("******"+myCred.getSpiName());
            // Specify the reason to sign the document
            String reason = "The document was reviewed";
            // Specify the location of the signer
            String location = "New York HQ";
            // Specify contact information
            String contactInfo = "Tony Blue";
            // Create a PDFSignatureAppearanceOptions object and show date information
            PDFSignatureAppearanceOptionSpec appear = new PDFSignatureAppearanceOptionSpec();
            appear.setShowDate(true);
            appear.setShowReason(true);
            // Set revocation checking to false
            java.lang.Boolean revCheck = new Boolean(false);
            // Create objects to pass to the sign method
            OCSPOptionSpec ocspSpec = new OCSPOptionSpec();
            CRLOptionSpec crlSpec = new CRLOptionSpec();
            TSPOptionSpec tspSpec = new TSPOptionSpec();
            // Sign the PDF document
            Document signedDoc = signClient.sign(
                credDoc,
                fieldName,
                myCred,
                HashAlgorithm.SHA1,
                reason,
                location,
                contactInfo,
                appear,
                revCheck,
                ocspSpec,
                crlSpec,
                tspSpec);
            // Save the signed PDF document
            File outFile = new File("C:\\ConferenceReg_flatten_signed.pdf");
            signedDoc.copyToFile(outFile);
        catch (Exception ee) {
            ee.printStackTrace();
