First off, I just have to correct your terminology. "exec" is a
statement, and doesn't require parentheses, so talking about "exec()"
invites confusion.
I'll answer your question in terms of eval(), which takes a string
representing a Python expression, interprets it, and returns the result.
In Python 2.3, the following works right: u'\u0190'
Here, the string passed to eval() contains the literal LATIN CAPITAL
LETTER OPEN E, and the expected Unicode string is returned
The following behaves "surprisingly": '\xc6\x90'
.... you seem to get the UTF-8 encoding of the Unicode.
This is related to PEP 263 (
http://www.python.org/peps/pep-0263.html)
but the behavior of compile(), eval() and exec don't seem to be spelled
out.

To expand on Jeff's reply:
in the first example, he's passing a Unicode string to eval(),
which contains a Unicode string that contains a Unicode escape.
The result is a Unicode string containing a single Unicode character.
In the second example,
he's passing a Unicode string to eval(), which string contains
a ***normal*** string that contains a Unicode escape. The
Unicode escape produces two characters. The result is a
***normal*** string that contains two characters.
Is this your problem?
