Do you mean the Windows Command Prompt shell?

cp949 is a Euro-Korean multibyte encoding whose mapping is given at
http://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WINDOWS/CP949.TXT
u1368 is not in the mapping. There is no reason the utf-8 site would 
restrict itself to the cp949 subset.

Perhap it prints in the interpreter because 2.x uses errors = 'replace' 
rather than 'strict' (as in 3.x).

Try print rf.read().decode('utf-8').encode('cp949', errors = 'replace')
Non-cp949 chars will print as '?'.

because IDLE encodes to utf-8, and x.decode('utf-8').encode('utf-8') == x

Printing utf-8 encoded bytes as if cp949 encoded bytes is pretty hilariour

  or how to print the not broken strings.
