The pdfcreator is a good tool to generate high quality and small size pdf files I have ever seen.
But it would generate weird bold Chinese characters, here is the example:
1. PDF created via pdfcreator

2. pdf created via other tools
image url is: http://www.watertools.cn/images/other/other_bold.png
you can see the differences.
Could anyone fix this?
