Urdu italic characters are rendered as square in output PDF using .NET

Aspose Words for Java saves italic Urdu characters as squares in exported PDF. Please see following code:
package test;

import com.aspose.words.Document;
import com.aspose.words.ProtectionType;
import com.aspose.words.SaveFormat;

import java.io.File;

public class Main
{
    public static void main(String[] args) throws Exception
    {
        String sourceFile = new File("source.docx").getAbsolutePath();
        String targetFile = new File("target.pdf").getAbsolutePath();
        Document asposeDoc = new Document(sourceFile);
        asposeDoc.removeMacros();
        asposeDoc.protect(ProtectionType.NO_PROTECTION);
        asposeDoc.save(targetFile, SaveFormat.PDF);
    }
}

In attachment you can find source.docx file. You will notice that third and fourth paragraphs have italic style applied. Letters from these paragraphs are converted into squares in resulting PDF.
