Hi There,

Is there any update on this ticket [PDFNEWNET-39002]. We are currently blocked and are not able to use unicode characters in PDF.

Any ideas when the fix will be available?

Thanks, -Askhay

Hi Akshay,

Hi David,


Thanks for contacting support.

I am afraid the earlier reported issue is not yet resolved. However the earlier reported issue is logged against specific HTML file and in case you have some different scenario, please share the input document, so that we can test the scenario and share our findings. We apologize for your inconvenience.

Hi,


Thanks for your quick response.

The example I am using is the table below. The characters in ‘Arial’ font don’t appear in the PDF, but the ones in ‘Arial Unicode MS’ do. In my real examples the Chinese characters can be mixed with English so I can’t change the font overall.

Arial Arial Unicode MS
A 诶 A 诶
B 比 B 比
C 西 C 西

Hi,


we have found the following setting allows it to work. It works for the most common languages in our app. We didn’t need to change anything else.

Pdf pdf = new PDF();
pdf.IsAutoFontAdjusted = true;

Hi David,


I have tested the scenario with following code snippet using Aspose.Pdf for JAVA 17.3.0 on MAC OS and have managed to export HTML file to PDF successfully. I have also attached the PDF file for your reference.

JAVA

<span style=“background-color: rgb(255, 255, 255); font-family: “Courier New”, Consolas, Courier, monospace; font-size: small; white-space: pre;”>HtmlLoadOptions htmloptions = <span class=“kwrd” style=“font-family: “Courier New”, Consolas, Courier, monospace; font-size: small; white-space: pre;”>new<span style=“background-color: rgb(255, 255, 255); font-family: “Courier New”, Consolas, Courier, monospace; font-size: small; white-space: pre;”> HtmlLoadOptions(dataDir);
Document doc = new Document(dataDir + “test.html”, htmloptions);
doc.save(dataDir + “htmltopdf.pdf”);

If you still face any issues, please share your environment details to reproduce the issue on our end.

We are sorry for this inconvenience.

Hi David,

Thanks for contacting support.

Adding more to Fahad's comments, it appears that you are using legacy aspose.pdf.generator approach for HTML to PDF conversion. However as suggested by Fahad, please try using new DOM approach.

The issues you have found earlier (filed as PDFNET-39002) have been fixed in Aspose.PDF for .NET 24.1.
