emacs-unicode-2: every line begin with #xd7 and #xf7 becomes gibberish

[Zhang Wei]

If a line begin with ×(unicode code point #xd7) and ÷(unicode code point
#xf7) and then several chinese characters, this line will becomes
gibberish after `C-l'(recenter). But there's no problem if these two
characters are in the middle of a line.

Same problem under GNU/Linux and M$ Windows.
