It was a problem with the handling of fancy quotes in a DBCS encoding 
(as used for CJK languages).  We don't attempt to use them for 
sQuote(), and will no longer attempt to use them for help.  This will 
take effect in r49952 and later, and seems to work for me in CP936.

It is not easy for us to test in Chinese Windows (most non-Chinese 
editions do not support it, or need add-ons installed), so please keep 
on reporting issues, particularly those with help (text, HTML, PDF?) 
rendering.
