Topic: CJK vertical writing

I am new to PDF development and I have a question about CJK vertical writing. What is the official way to handle CJK vertical writing? I have inherited code of a virtual printer driver that doesn't handle vertical writing correctly. I somehow managed to rotate the glyph to the right orientation but the position is way off. The spec mentions a WMode attribute in the CMap structure but I can't fully understand it. Can someone briefly explain how I should handle CJK vertical writing? Is there any good online references or books about this topic? Thanks in Advance.
