Open source OCR for Chinese

I've searched around for open source OCR for Chinese. But without any luck there rarely seems to be some open source OCR (for Chinese) that are usable.

So I am here wondering:

Is there any open source OCR for Chinese that could be used for production environment?
What's the main differences when implementing an OCR for Latin-languages and for Chinese? I know some good OCR such as Tesseract or Ocropus, what should I do if I want to make it support Chinese?

Any help is appreciated and thanks in advance~

Chinese has far more characters than Latin languages. There are some commercial products. One of the ways is to contact them and get help.

I don't think there is an open source for Chinese or Japanese characters. In the area of OCR, there are a lot of techniques beyond the pattern recognition algorithms, where a company is good at, not the open source community.
