                You  point out a very important issue that Windows 2000
traditional chinese version caused .
These characters can be copy and past to different AP or using the same text
file but select different AP to display it:
      1. notepad
      2.wordpad
      3.IE address BAR
      4.Mail body
      5.MicroSoft word
You can find a terriable results , all the font/script will change to
different style depend on different font size selected  as it is Japanese,
Taiwanese or Chinese scripts that you described.  There are not all the same
in different AP !!!
      These are the traditional variant coexisted in UNICODE table.  In
Taiwan,  people treat these pair as the same , not as you described that
which one is Japanese, PRC, Korean or Taiwan.
