Hello,

Thank you for your inquiry.
I have tested the Word document you provided using Spire.Office for Java Version: 9.1.4, but I was unable to reproduce the issue you mentioned. I noticed that you are not using the latest version of Spire.Office, so please upgrade to this version for testing. Your license is valid for this version, and there have been some changes in how the license is used. Please refer to the code below.
Please note that your license is valid for this version, as there have been changes in the licensing usage for this specific version. Please refer to the code snippet below for further guidance:

Code: Select all

com.spire.doc.license.LicenseProvider.setLicenseKey(LICENSE_KEY);
com.spire.doc.license.LicenseProvider.loadLicense();
com.spire.license.LicenseProvider.setLicenseKey(LICENSE_KEY);
com.spire.license.LicenseProvider.loadLicense();

Additionally, I noticed that your Word document uses the "Open Sans" font, which is not present in the PDF file you provided. Please install this font and test with the latest version.

Sincerely,
Annika

Hello,

Thank you for providing your feedback.
Based on your description, I believe you manually imported the Spire.Office JAR file. Please note that starting from Spire Office 9.1.4, Spire.Doc is independent of Spire.Office. If you manually import the Spire.Office JAR file into your project, you also need to import the latest version of the Spire.Doc JAR file.
However, if you are using Maven to import Spire.Office, Maven will automatically import Spire.Doc for you.
If you have any further questions or require assistance with the integration, please let me know.

Sincerely,
Annika

Hello,

Thank you for your feedback.
I have checked the PDF file you provided and found that the "Open Sans" font has not been embedded, leading to the display of garbled text. Please refer to the following code to load the custom font to solve this issue.

Code: Select all

...
//The "Fonts" folder contains the "Open Sans.ttf" file
Document.setGlobalCustomFontsFolders("Fonts");
Document document = new Document();
...

Hello,

Thank you for your feedback.

I have retested the Word document you mentioned, but I was unable to reproduce the issue you encountered. I have attached my testing project, which includes the resulting file "result.pdf". Please download and test it accordingly. Please note that the testing code is located in the "src/test" directory, not in "src/main".

If the issue persists after testing, please provide your test environment, such as OS info (E.g. Windows 7, 64-bit) and region setting (E.g. China, Chinese), so that we can further investigate and assist you.

Thank you once again for your cooperation.

Hello,

Thank you for your feedback.
Based on the information you provided, I tested the project previously provided to you in a Windows Server 2019 environment, but there were no issues either. May I ask if you tested the project I provided to you earlier? What was the result?
Also, the reported error you mentioned I guess it should be caused by the conflicting jar package reference of Spire.Pdf. Please check if you have only the latest versions of our Spire.Office and Spire.Doc installed in your project.
