Hi,

It seems that it occurs when 'encoding' is changed from the default setting.
(E.g. set enc=utf-8 on Windows.)

The following patch should fix the problem:

P.S. If you report a problem related to multibyte characters, it's better
to show your 'encoding' setting and your OS version.

Regards,

Yes, I'm on Windows and I have `set enc=utf-8` in my vimrc.
Thanks for the patch. Hope it to be merged.
