Set UTF8 Encoding & Transform MHT File with Chinese Characters to PDF | C# .NET

[ericbesson]

Hi,

I’m using Aspose.Net/) nuget C#, and a want to convert MHT file to PDF.
In my case, the MHT is converting to PDF but all the page contain “chinese” caracteres

• orginial file
• pdf result
• word document is correctly converted
• https://i.ibb.co/zs8g50n/image.png
• result.zip (1.1 MB)

code :

var doc = new Aspose.Words.Document(inStream);
doc.Save(outStream, Aspose.Words.SaveFormat.Pdf);

With the online converter the render is good : https://products.aspose.app/pdf/fr/conversion/mht

Using : aspose.pdf\21.6.0

Thx
Eric

@ericbesson,

Regarding WORDSNET-22549, we suggest you to please define encoding explicitly because it is not always possible to automatically detect encoding correctly.

LoadOptions opts = new LoadOptions();
opts.Encoding = Encoding.UTF8;
Document doc = new Document("C:\\Ajout MHT d'indisponibilité du candidat en TT ROUAUD Gregory de l'agence RENNES FREVILLE.mht", opts);
doc.Save("C:\\21.7.pdf");
