Issue with file size after saving Doc file

Hi,
When testing with Aspose Word, I found an issue with file size increase x2 times after loading and saving it back to Doc format.
For more detail, I have a collection of document (doc file) which contains huge text data. I see that Word application use 1 byte for character. But after open and save it back to Doc file use Aspose Word, these chars use 2 bytes.
Here is sample code (Just load the document then save it):

Document doc = new Document(inputDocFile);
doc.Save(@"D:\\out.doc", SaveFormat.Doc);

And this is sample files and output file of them : sample.zip (921.2 KB)

I’m using latest version of Aspose 23.5.0 too.

Please help me with this case. Thank you.
