I’m using aspose.pdf version 10.5.1.0 to set document info for a PDF file. And I met a problem, and this problem seems easier to reproduce with your sample code.
The code snippet as bellow
//specify document information
DocumentInfo docInfo = pdfDocument.Info;
docInfo.Keywords = “This is test ++ 未”;
//save output document
pdfDocument.Save(dataDir + “SetFileInfo_out.pdf”);
The problem is that, if the “Keywords” contains some Chinese word, like “未” , and also with special word “++”, then after saved the pdf, and open this pdf via Adobe Reader to check the Keywords, found that all of these special words “++” is missing!!
Can you explain and guide me how to resolve this issue?
