=== NOTE ===

The CJK font selection will be performed in the following order:

 1. /usr/local/share/ghostscript/Resource/Font/<fontname>

 2. /usr/local/share/ghostscript/Resource/CIDFont/<fontname>

 3. /usr/local/share/ghostscript/7.07/lib/CIDFnmap

So, to use CIDFnmap you have to make sure that there is no font file that
has the same name as you want to customize in Resource/Font and
Resource/CIDFont.
