AR PL KaitiM is always the first match?

[Deling Ren <lg@home.homeunix.org>]

I installed the package ttf-arphic-gkai00mp on my sid box and now gtk  
widgets are using "AR PL KaitM" to display English characters, which  
is not what I want. I wanted to use Bitstream Vera Sans instead. The  
font.conf file is the one that comes with sid by default. And when I  
run fc-match with an empty pattern, it always returns "AR PL KaitiM".

I guess the reason is I set LC_CTYPE to zh_CN.gbk for Chinese input.  
Is there anyway that I can have the Chinese input and not using the  
Chinese font to render ASCII characters?

Thanks a lot. And I am using xfce 4.2 and fcitx if that matters.
