Yeah, this indeed causes the problem.  utf8->cp936->utf8.  
As we have discussed in this thread, cp936 is in fact gbk, which
sometimes is not friendly to our enc-cn (aka gb2312) users when your
file contains a gbk-only character that does not exist in the gb2312
encoding.

We want our vimcdoc as much encoding-independent as possible.  Users can
use euc-cn/gb2312, gbk/cp936, utf8 and they dont have to know about the
underlying conversion that Vim itself has done when displaying the help
file.  We make this transparent to users and they dont have to bother
doing any conversion themselves.  They just :help and see.

This means we translators have to
1) edit our file utf-8 native. we dont manually do any conversion
whatsoever.
2) make sure the utf8-encoded file _can_ be successfully converted to
gb2312, since gb2312 is the very subset.

I think fileencodings=utf8 is the rite way to go.  FYI, it does not
treat _all_ files as utf-8.  It just treats utf8 (which includes ascii)
files as utf8.

Well, this only ensures the condition 1) above.  If you write some 'evil'
characters, the file still cannot be converted to gb2312.

I wonder if there are similar tools on Windoze like this:
$ iconv -f utf-8 -t euc-cn file > /dev/null
which can help you check the validity.

Checked, ok.
