# fix a  bug in LWP   'usc-cn' can not be recognized correctly.
#  
#  when i  use  method  HTTP::RESPONSE::decoded_content ,that can not decode 'usc-cn' html 
#  but it  use 'iso-8859-1' to decode html.
#  though   'iso-8859-1'  is  a universe code , the decode method can work well.
#  but    HTTP::RESPONSE::content_charset  can not get the right code name  .
# 
#   there are two causes   
#　　　　　　　　　one  is   Encode::Encoding::mime_name can not get usc-cn,  usc-cn is not in the IANA charset name list.
#                  the other is   HTTP::RESPONSE::decoded_content havdn't implement  usc-cn decode,we only can use iso-8859-1 to replace.
