Wrong font for accented characters, after PDF -> Word doc conversion

Hello,

When converting a PDF to a Word doc with Aspose, the font of accented characters is changed to Calibri.

Attached files:
test.pdf: the original PDF file
test.doc: the Word document generated by Aspose, from the above PDF. The text uses the Times New Roman font, except for accented characters which are in Calibri. This is a bug, the whole text should use the same font.

C# code:

        public byte[] GetWordDocument()
        {
            using (MemoryStream inStream = new MemoryStream(File.ReadAllBytes(@"C:\test.pdf")))
            using (MemoryStream outStream = new MemoryStream())
            {
                Aspose.Pdf.Document pdf = new Aspose.Pdf.Document(inStream);
                pdf.Save(outStream, Aspose.Pdf.SaveFormat.Doc);
                return outStream.GetBuffer();
            }
        }

Can anyone confirm this problem, and suggest a workaround?
Thanks.
