Many characters of these two set of Chinese(in fact, including Chinese 
Characters in Japanese  and Korean...) are the same. Aren't they encoded 
to the same codes when they are identical?

There punctuations are those commonly used in China.
There Chinese characters are randomly pickup from
http://www.khngai.com/chinese/charmap/tbluni.php?page=0
(from all the six pages.)

maybe 226 to 239 is the range I need.
