knowing Shelfari deeper

This morning, when I signed in Shelfari and tried to search a Chinese book, I met problems. I could not find any result about any Chinese books. It's so disppointing that it only supports English, Franch, German, and Spanish. Then, when I wanted to upload my Chinese books, I still had problems. It couldn't display Chinese characters either. What a world do we have? I felt so frustrated after several times trying to replace the Chinese chararcters of the title and author name with English but fail.
