PDFs and Japanese and weirdness and bugs

G'day:
Here's one I was looking at on Stack Overflow today. It involves generating a PDF with Japanese text in it. I did not solve the issue. This doesn't surprise me too much, because I have never once generated a PDF in CFML in a production environment. I've just never had the need to. My entire exposure to <cfdocument> is in situations like this: investigation and "helping" other people.
