The encoding of your console is 'cp949', so when you try to print the
Unicode string, Python tries to encode it as 'cp949'.

Unfortunately, the character (actually, when talking about Unicode the
correct term is 'codepoint') u'\u1368' cannot be encoded into 'cp949'
because that codepoint does not exist in that encoding, in the same way
that ASCII doesn't have Korean characters.

So what is that codepoint?

 >>> import unicodedata
 >>> unicodedata.name(u'\u1368')
'ETHIOPIC PARAGRAPH SEPARATOR'

Apparently 'cp949', which is for the Korean language, doesn't support
Ethiopic codepoints. Somehow that doesn't surprise me! :-)
