 It's indeed a great news.

 As some people ask me about the preformance of Chinese system,
 I would like to clarify something.
 First, I mention "slow" because it is noticable,
 but it does not prevent me from normal use.
 Second, it happends on a lot of application/toolkit/platform/OS I ever 
used.
 Even the Mac is slow when handling a lot of Chinese text.
 (IE on windows is fast by the way. :)
 I'm comparing the Chinese vs latin, not GNUstep vs other system (windows, 
GTK, etc).
 Therefore, GNUstep with Chinese does not slower than any other system.
 I think it always involves in cache and optimization.
 The reason that I mention the performance with Chinese is because I notice 
it,
 not because I complain it. Kind of used to it.
 Hope people won't have an impression that text system of GNUstep is slow.
 It's not, and it is not optimized for CJK yet.
