When saving the Word file to pdf file, Pdf file show wrong format in thai language.

Please upgrade to the latest (20.7) version of Aspose.Words for .NET and try running the following code:

Document doc = new Document("E:\\temp\\Thai.docx");
doc.LayoutOptions.TextShaperFactory = Aspose.Words.Shaping.HarfBuzz.HarfBuzzTextShaperFactory.Instance;

We have installed the font file that you shared and then converted your “Input Word.docx” to PDF by using the code from my previous post and attached the PDF file here for your reference:

Regarding the exception you shared in “comparison screenshot.png”, please first remove Aspose.Words for .NET and Aspose.Words.Shaping.HarfBuzz references from your visual studio project. After that install the ‘latest 20.7 versions’ of Aspose.Words for .NET and Aspose.Words.Shaping.HarfBuzz packages from NuGet. Hope this helps.
