Hi,
I'm running the test:
$ python sample_scripts/consistency_tests.py
and this uncovered another non-standard character.  Probably this one:
-        Fushman et al. (1998) Direct measurement of 15N chemical shift 
anisotropy in solution. J. Am. Chem. Soc., 120: 10947–10952.
+        Fushman et al. (1998) Direct measurement of 15N chemical shift 
anisotropy in solution. J. Am. Chem. Soc., 120: 10947–10952. 
http://dx.doi.org/10.1021/ja981686m
This is a long '-' character, an m-dash, causing the failure.
Regards,
Edward
