[pdftex] Vietnamese fails to print some particular phrase

[Prabhu]

Here I have attached the Vietnam.tex file.  On running the command *pdflatex
Vietnam.tex *, it throws the below error.



! Package ucs Error: Please activate option 'combine'.



See the ucs package documentation for explanation.

Type  H <return>  for immediate help.

 ...



l.11 Mặ

          c găng tay bảo vệ / quần áo bảo vệ / trang bị ba...



Please guide me in,

   1. The second phrase is giving the error. What is the problem in the
   second phrase?
   2. How to activate the option combine?
   3. Or any other way to solve the problem?



I’m using

Emacs Version:  GNU Emacs 21.4.1

LaTeX version:   pdfeTeX 3.141592-1.21a-2.2 (Web2C 7.5.4)
  kpathsea version 3.5.4


Thanks.
