:right command on Chinese characters

When I run :right command in gvim, it's ok, like this:

                       彼外道常说自然，我说因缘。——楞严经

But if I open the txt file with Word, it's like this:

                        彼外道常说自然，我说因缘。——楞严

经

The last character is returned to the next line, what's wrong?
