Okay, I'll use one of the CJK codecs as the example. EUC-KR is the
default encoding.
>>> import sys;sys.getdefaultencoding()
'euc-kr'
>>> 'íê'
'\xc7\xd1\xb1\xdb'
>>> u'íê'
u'\ud55c\uae00'
>>> s=compile("inside=u'íê'",'','single')
>>> exec s
>>> inside #wrong
u'\xc7\xd1\xb1\xdb'
>>> s=compile(u"inside=u'íê'",'','single')
>>> exec s
>>> inside #correct
u'\ud55c\uae00'
So I reckon that the "compile" should get a unicode object. However...
C:\Python24\Lib>python code.py
> <string>(1)?()
(Pdb) c
Python 2.4 (#60, Nov 30 2004, 11:49:19) [MSC v.1310 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.

>>> 'íê'
'\xc7\xd1\xb1\xdb'
>>> u'íê' #wrong.. should be u'\ud55c\uae00' instead
u'\xc7\xd1\xb1\xdb'
>>> import sys;sys.getdefaultencoding()
'euc-kr'
>>> ^Z
Am I right that I assume the problem lies in the code.py(and therefore
in codeop.py)? To correct the problem, I seem to parse each string and
change the literal unicode object... Hmm... Sounds a bad approach.
