db_url does not handle '#' in password?

[lisac]

I'm trying to configure a database password that happens to contain a #. Is that character not supported in this package's processing of the database url? When I alter the test_postgres_parsing in test.py so that the password contains that character, eg wegauwhgeuioweg --> weg#auwhgeuioweg, the test encounters this error:

ERROR: test_postgres_parsing (environ.test.DatabaseTestSuite)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "c:\projects\django-environ\environ\test.py", line 241, in test_postgres_parsing
    url = Env.db_url_config(url)
  File "c:\projects\django-environ\environ\environ.py", line 371, in db_url_config
    'PORT': _cast_int(url.port),
  File "C:\Python27\Lib\urlparse.py", line 113, in port
    port = int(port, 10)
ValueError: invalid literal for int() with base 10: 'weg'

I've found that other special chars, such as these: }{)(}|!\^><; can be embedded in the database password and not break the test. For example, when I alter the password from wegauwhgeuioweg to :wegauw}{)(}|!\^><;hgeuioweg on lines 238 and 245 of the test case in test.py, no tests fail.

My environment is python 2.7.10.

Summary: Is it true that a # included in the db password will corrupt the db url?

Some characters must be encoded to avoid beaking the url parsing.
See #48

Fixed with #69

This is still issue in 0.4.5

import environ

os.environ['a'] = 'mysql://engineuser:i!kkGhs#$j57@127.0.0.1:3306/mydb'
