Behavour of django.utils.text.slugify is not consistent

[Marcos Diez]

After hours of debugging, I realized the behavior of django.utils.text.slugify is not consistent.

On Python 2.7.12 and Python 3.5.2 ( Ubuntu 16.04 LTS)

from django.utils.text import slugify


original_value = ('test trial', )
slug = slugify(original_value)
print(slug) # returns "test-trial"

but on Python 2.7.12

from __future__ return unicode_literals

from django.utils.text import slugify


original_value = ('test trial', )
slug = slugify(original_value)
print(slug) # returns "utest-trial"

This is serious and inconsistent.
Fixing it is not trivial either because it may cause backwards incompatibility.

If I was in charge I would either:

• Do nothing since python 2.7 will be deprecated
• Deprecate slugify and create slugify2 which is not affected by this bug

Thanks for your time,
