We are creating pdf documents in our business system containing chinese text and therefore using Windows SimSun font as default. Pdf files shows up correctly in Windows Vista, 7 and 8 but in Windows XP it displayes incorrect characters.
If I copy and paste the text from pdf to Notepad in Windows XP and select the SimSun font it diplayes correct characters. Problem is in Adobe Reader, we have tested from ver 9 and up to the latest but still showing incorrect characters.
Any ideas on why this is happening on Windows XP ?
