It is great to know that you have Chinese language support within the menu interface on your roadmap for this year. I am using your product now in anticipation of this feature and really like the fact it supports Chinese characters within the content pages. It works great when I am creating a new document and then publish it, however, when I edit the document, the Chinese characters turn into question marks. Is there any solution to preserving all the character text when I want to edit the document?
I think you may have uncovered a new issue. I've logged this issue as CS-1644.
Unfortunately at this time I do not have a workaround for you. If I uncover one prior to the 1.6 release I'll update this thread with the details.
