Description Anantha Keesara 2008-10-24 15:15:09 PDT 
I Steps:
 Go to  http://next.atnext.com/template/next/front.cfm
 
 II Issue:
 In left nav bar , the image has a caption. In webkit, caption is not showing in Chinese. Instead $av_caption$ is seen.
 
 III Conclusion:
 The issue here is PCRE handles \a as a special character, but the regexp engine in FF and IE does not treat it as special.  
 FF just ignores the backslash if the character following it is not special.
 
 IV Other Browsers:
 IE7: ok
 FF3: ok
 
 V Nightly tested: 37819

Works for me.  I'm guessing this was a bug in our use of PCRE, since replaced.
