I have a MS Word 2000 document in Chinese characters.  I found that when I
copy and paste the content to a blank new MS Word 2000 document, formatting
with the same margins, some lines cannot have the same number of Chinese
characters as the original document, even though all format settings in two
documents are the same.   It seems that some (but not all) Chinese characters
are of a slightly different width in two documents, so the difference is just
one character per line. It also looks like that there is something wrong with
the original document because when it is converted to a PDF by Acrobat, the
number of characters for some lines has also been changed.  Does any one
experience the same or similar and can anyone tell what's wrong with the
original document?
