Chinese character in bookmark display wrong

Hi,

Hope you are doing well!

It could be a font specific issue. Please help me with few questions to understand your issue better:

1. Is it happening with all the PDF's ?
2. Is your application updated ?

There is a posibility you might need to download the required font maually.
