Hi Team,
On transforming an EML file to PDF, the output is obtained with incorrect font. Following code was used for processing:

    MailMessage message = MailMessage.load("C:\\Users\\Administrator\\Desktop\\HindiFont.eml");
    MhtSaveOptions mhtSaveOptions = new MhtSaveOptions();
    mhtSaveOptions.setMhtFormatOptions(MhtFormatOptions.WriteHeader | MhtFormatOptions.HideExtraPrintHeader|MhtFormatOptions.DisplayAsOutlook);
    String mhtFile = "C:\\Users\\Administrator\\Desktop\\Hindi_Font.mhtml";
    message.save(mhtFile, mhtSaveOptions);
    HtmlLoadOptions loadOptions = new HtmlLoadOptions();
    loadOptions.setLoadFormat(LoadFormat.MHTML);
    Document document = new Document(mhtFile,loadOptions);
    document.save("C:\\Users\\Administrator\\Desktop\\HindiFont.pdf");

Attaching the input and outfput files here: Aspose.zip (75.0 KB)

Thanks,
Sumeet.

@sumeetm,

We have internally verified the issue w.r.t Aspose.Email and it does not seems to be an issue with API as we exported the EML file to MHT using MS Outlook and then used Aspose.Words to save that as PDF. That too hindi font issue in exported PDF. I have requested concerned team to take on further from here and will assist her shortly.
