Unknown char V message when converting from pdf to pdfa

Aspose.PDF Product Family
1

I have a 2 page document which I am trying to convert from pdf to pdf-a using the following code.

try (final Document pdfDocument = new Document(inputFile.getAbsolutePath())) {
    pdfDocument.convert(xmlPath + "/log.xml", PdfFormat.PDF_A_1A, ConvertErrorAction.Delete);
    pdfDocument.save(outputFile.getAbsolutePath());
}

The conversion fails with the following error.

Is this due to an unknown font or something else? Is there any setting changes I can make to the Document to fix this?
