SA 3.0.7/Chicago (note) treats one author as three different authors; probably, encoding related

After quoting several pieces by a German author, whose names contains an Umlaut, I get this when generating the bibligraphy:

Habermas, Jürgen. Erläuterungen zur Diskursethik. 5. Aufl. Frankfurt am Main: Suhrkamp, 1991.
———. Moralbewußtsein und kommunikatives Handeln. Frankfurt am Main: Suhrkamp, 1983.
Habermas, Jürgen. Theorie des kommunikativen Handelns. Bd. 1. 2 Bd. Frankfurt am Main: Suhrkamp, 1981.
———. Theorie des kommunikativen Handelns. Bd. 2. 2 Bd. Frankfurt am Main: Suhrkamp, 1981.
Habermas, Jürgen. „Three Normative Models of Democracy“. Constellations 1, Nr. 1 (1994): 1–10.

Of couse, what I wanted was this:

Habermas, Jürgen. Erläuterungen zur Diskursethik. 5. Aufl. Frankfurt am Main: Suhrkamp, 1991.
———. Moralbewußtsein und kommunikatives Handeln. Frankfurt am Main: Suhrkamp, 1983.
———. Theorie des kommunikativen Handelns. Bd. 1. 2 Bd. Frankfurt am Main: Suhrkamp, 1981.
———. Theorie des kommunikativen Handelns. Bd. 2. 2 Bd. Frankfurt am Main: Suhrkamp, 1981.
———. „Three Normative Models of Democracy“. Constellations 1, Nr. 1 (1994): 1–10.

The whole thing appears to be related to the entries using different encodings; the following Python output corrobaretes this suspicion:

Python 2.7.1 (r271:86832, Jul 31 2011, 19:30:53) 
[GCC 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2335.15.00)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> len("Habermas, Jürgen") # First occurrence
17
>>> len("Habermas, Jürgen") # Second occurrence
18
>>> len("Habermas, Jürgen") # Third occurrence
17

The difference between the first and third occurence is somewhat curious:

>>> [f for f in "Habermas, Jürgen"] # First occurrence
['H', 'a', 'b', 'e', 'r', 'm', 'a', 's', ',', ' ', 'J', '\xc3', '\xbc', 'r', 'g', 'e', 'n']
>>> [f for f in "Habermas, Jürgen"] # Second occcurrence
['H', 'a', 'b', 'e', 'r', 'm', 'a', 's', ',', ' ', 'J', 'u', '\xcc', '\x88', 'r', 'g', 'e', 'n']
>>> [f for f in "Habermas, Jürgen"] # Third occurrence
['H', 'H', 'a', 'b', 'e', 'r', 'm', 'a', 's', ',', ' ', 'J', '\xc3', '\xbc', 'r', 'g', 'e', 'n']

I've got no idea where the second "H" in the third occurrence is coming from. Thanks for looking into this.

Did you import these items from websites? If so, can you provide the URLs?

odin

I've imported:

(1) "Erläuterungen zur Diskursethik" and
(2) "Moralbewußtsein und kommunikatives Handeln"

from Amazon and, in all likelihood, but I can no longer tell for sure,

(5) "Three Normative Models of Democracy"

from the journal's webpage; the journal is now with Wiley, but it's a while since I've downloaded the paper.

The other two, I've entered manually:

(3) Theorie des kommunikativen Handelns, vol. 1, and
(4) vol. 2

Oh, I forgot the URLs:

(1) http://www.amazon.de/dp/3518285750
(2) http://www.amazon.de/dp/3518280228

I don't have an URL for (5).
