If it's of any help, in a post on 2007-07-22 by Peter Otten,
(though I can't get a url for it at the moment) he took the
same approach. From a saved copy of that post:
import encodings
import os
import glob
def encodings_from_modulenames():
ef = os.path.dirname(encodings.__file__)
for fn in glob.glob(os.path.join(ef, "*.py")):
fn = os.path.basename(fn)
yield os.path.splitext(fn)[0]
