high CPU load under zh_CN-UTF-8 locale

[bxuefeng]

Hi unicoders,

I am having a strange problem: when I change the locale from en_US.UTF-8 into
zh_CN.UTF-8, I noticed a heavy usage of CPU time cycle when launching urxvt.
When I reset the locale back to en_US.UTF-8 the probem is gone. 

What might causing this problem? 

my system configurations are:

Debian/Sid

rxvt-unicode (urxvt) v7.0 - released: 2006-01-13
options: xft,styles,combining,blink,iso14755,encodings=eu+vn+jp+jp-ext+kr+zh+zh-ext,fade,XPM,transparent,tint,utmp,XIM,scrollbars=plain+rxvt+NeXT+xterm,frills,selectionscrolling,wheel,slipwheel,smart-resize,cursorBlink,pointerBlank,
