Running postgres_database.present a second time causes error "has wrong parameters which couldn't be changed on fly"

Question

Running a salt state that looks like the following to create a postgres database for django...

django-db:
  postgres_database.present:
  - encoding: 'UTF-8'
  - owner: djangouser
  - db_user: postgres

When I run it the first time, so far, so good:

      ID: django-db
Function: postgres_database.present
  Result: True
 Comment: The database django-db has been created
 Started: 20:59:01.148225
Duration: 494.007 ms
 Changes:
          ----------
          django-db:
              Present

But when I run it again, the result is an error:

      ID: django-db
Function: postgres_database.present
  Result: False
 Comment: Database django-db has wrong parameters which couldn't be changed on fly.

Credit to user martin_ on IRC, The problem is the hyphen in 'UTF-8'. The state should be

django-db:
  postgres_database.present:
  - encoding: 'UTF8'
  - owner: djangouser
  - db_user: postgres
