Hi,

I attached a sample of the problem we were able to recreate by chance.
As you can see, some are rendered as question marks, some are corrrectly rendered in chinese.

additionally this does not happen frequently. most of the time everything is in order (rendering).

our working hypothesis that if the server slows down due to usage it affects the rendering.

Is there any solution that can resolve this?
We have our doubts on adding a new font in the properties file will work:

SimSun=arialuni.ttf

appreciate on any advise on the matter. thanks!
