The problem is not displaying texts but text input. As you know, input of Chinese, Japanese, Vietnamese and Korean is not trivial. There is a community project attempting to make some of them work in the N900, as someone mentioned. Not yet available for the N900 but, then again, the device itself is still not in the shops.
