1) It has never been our intention to localize this game to any other languages and we would like people to understand and respect this.
2) AGS does not currently support Chinese. ANSI is a 1-byte encoding system, which means it's limited to 256 characters. There is currently a beta version in the works that will include Unicode support and thus will make the use of full Chinese font sets possible, but it is still in development. Hopefully it will be functional by the time we start working on our next game.
