I am going through the GeoDjango tutorial from the official documentation.
  1. I have installed the required geospatial libraries, installed and enabled spatial functionality by extending the PostgreSQL via postgis.
  2. Downloaded the world borders data, and have unzipped the data.
  3. Created a GeoDjango model (WorldBorder) in the world app.
  4. Created the load.py inside the world app, as instructed in the documentation.
But when I try to import the load module and call the run routine, I am getting an error:

  Failed to save the feature (id: 141) into the model with the keyword arguments:
  Traceback (most recent call last):
    File "/home/vagrant/.virtualenvs/testenv/lib/python3.6/site-packages/django/contrib/gis/utils/layermapping.py", line 577, in _save
      stream.write('%s: %s\n' % ('Updated' if is_update else 'Saved', m))
  UnicodeEncodeError: 'ascii' codec can't encode characters in position 7-8: ordinal not in range(128)
  During handling of the above exception, another exception occurred:
  Traceback (most recent call last):
    File "<console>", line 1, in <module>
    File "/vagrant/geo_project/world/load.py", line 30, in run
      lm.save(strict=True, verbose=verbose)

    File "/usr/lib/python3.6/contextlib.py", line 52, in inner
      return func(*args, **kwds)

      stream.write('%s\n' % kwargs)
  UnicodeEncodeError: 'ascii' codec can't encode character '\xc3' in position 62: ordinal not in range(128)

I am using these version:

gdal-bin v2.2.3+dfsg-2

Python v3.6.5
Django v2.1
psycopg2 v2.7.5
postgis v2.4.3+dfsg-4

I cannot figure out where I am wrong. Could you please help me out? Thank you.

This is most probably an error in the tutorial. Recent versions of GDAL
seem to automatically convert shapefile string encoding to unicode, so
the `encoding=iso-8859-1' parameter of the LayerMapping should be left out.
Could you confirm?

To close the thread, Benjamin used the solution in this thread (https://groups.google.com/forum/#%21topic/geodjango/Imkq2DDI7qg) to solve his issue.

Nevertheless, I committed this fix in the documentation:
