Hi @ava5412 , sorry for the late reply. We truly appreciate your feedback.

The sample document uses the Times New Roman font series, but since the PDF file does not embed this font and the mobile system does not have it pre-installed, the related text cannot be displayed properly. This issue also exists in version v2.0.1.

To resolve this, you can manually import the Times New Roman font and set it as the default font by referring to the following code. We sincerely apologize for the inconvenience and will continue to optimize font support.

// First, copy the Times New Roman.ttf file to the filesDir directory
String ttfPath = new File(getFilesDir(), "Times New Roman.ttf").getAbsolutePath();  
CPDFSdk.setDefaultFontPath(this, ttfPath);  
CPDFSdk.useDefaultFont(true);  
CPDFSdk.init(this, "your compdfkit license", true);

Hi @youna12345
This solution creates other problems:

1. Times New Roman font cannot be used freely due to license.
2. After applying these solutions, compatibility with PDF test files is broken.
3. The file cannot be fully saved for further printing using saveFontSubset, some lines are lost.
