Hi Anwender,
Apologize to ask questions on your topic.

Hi Awais.hafeez,
Thank you so much for your help.

*Note: The content in my file is “Thai” characters.

The command to convert the PDF file is as following:

Aspose.Words.Document docx = new
Aspose.Words.Document(sourcePath + @"\Source.docx");

string filePdf = destPath + @"\Destination.pdf";
string hyphenFile = hyphenDic + @"\th_TH.dic";
Aspose.Words.Hyphenation.RegisterDictionary(“th-TH”, hyphenFile);

string systemFontFolder = Environment.GetFolderPath(Environment.SpecialFolder.Fonts);

string fontsFolder = HttpContext.Current.Server.MapPath(ConfigurationManager.AppSettings[“FontsPdf”].ToString());

Aspose.Words.Fonts.FontSettings fontSetting = new Aspose.Words.Fonts.FontSettings();

fontSetting.SetFontsFolders(new string[] { systemFontFolder, fontsFolder }, true);

docx.FontSettings = fontSetting;

Aspose.Words.DocumentBuilder builderDoc = new Aspose.Words.DocumentBuilder(docx);

builderDoc.PageSetup.PaperSize = Aspose.Words.PaperSize.A4;

docx.UpdatePageLayout();

Aspose.Words.Saving.PdfSaveOptions saveOptions = new Aspose.Words.Saving.PdfSaveOptions();

saveOptions.SaveFormat = Aspose.Words.SaveFormat.Pdf;

docx.Save(filePdf, saveOptions);

Do you have a solution to this problem?

Best regards.

@brunetta,

Unfortunately, your issue is not resolved yet. We have completed the initial analysis of this issue but I am afraid, because of complexity, the implementation of this issue has been postponed. There is no ETA available at the moment. We will inform you via this thread as soon as this issue will be resolved in future. We apologize for your inconvenience.

[brunetta]

Thanks for letting me know and I will wait to hear from you.

@brunetta,

Regarding WORDSNET-18424, there are following three problems:

• Incorrect positioning of Thai glyphs
• Incorrect line wrapping for Thai
• Thai distributed paragraph alignment.

The first issue can be solved by installing the Aspose.Words.Shaping.HarfBuzz package and then enabling it as explained in this article: https://docs.aspose.com/display/wordsnet/How+to+Use+OpenType+Features.

We are working on the other two issues and will keep you posted on further updates.
