The Chinese characters on the artboard are displayed as garbled characters.

@Rui Chen this is an ongoing issue with Chinese characters not reading properly in Xd. And chances of any new developments with this known bug, is highly unlikely as Adobe Xd is in 'maintenance mode'. Granted Xd just did a recent update likely for security patches, and maybe some known bugs...try updating to the new Xd if that solves it. If not, you might be out of luck, or try switching to English?
