We having the problem reading Chinese fonts
too.
We have consulted the lotus support in Malaysia,
they said we must install 3rd party software (e.g.. NJStar) to read Chinese
fonts. I tried install NJStar (trial version) ,
it work. But if we are going to install all legal copies of NJStar, we rather
change the whole email system to Microsoft Exchange Server.
We really regret purchased the IBM hardware system
which come with free Domino Server.
