I fully agree with you that a representing group is needed to facilitate
the communications and speak for Chinese users on all text layout issues.
I will make contact with the related people that I know, including Arne 
Gojge, the
maintainer of the Uni-fonts project, some Redhat developers in Beijing and
the Debian/Ubuntu Chinese group. I am not sure if my energy allows me
to change anything other than taking care of my project, but I will make
sure that your suggestions are passed around among those who are interested.

I am not sure if you noticed it or not, it has a language matching block 
before
strong binding to DejaVu Mono:

           <test compare="contains" name="lang">
                   <string>zh</string>
           </test>

it also matches WenQuanYi Bitmap Song in family, IMO, this strong 
binding will
only happen when user is under zh locales and has WQY font installed. 
So, I do
not think it will mess up Japanese fonts as it will not match the lang 
tag. I tested
it under ja locale, and everything seems to be normal (the mono font was 
not influenced),
the screenshot is attached.

hi Jens, I am not sure if my previous reply CCed you or not, but I want 
to know your
opinion and test results on this new font config file (attached). thank you!

thank you for reminding me this, I will do the according adjustment if
the config file get approved.

Again, I really appreciate your careful thoughts on these issues. All the
requests are quite reasonable. I will tailor my config file as best as I 
can
to avoid future complications.
