It means complete text is exist in the PDF but it is not visible. But if i select all text from the generated PDF file and paste it in the Notepad file then complete text ' 你好 Help ' is copied.
Now in the PDF file text ' 你好 ' is not visible only Text 'Help' is visible. Now i have converted this word file into the PDF file using the below code. In word document i am able to see all the text and all the style is applied in the text.
