The 2.10 version of #6685
Fixes #6684

  • url in question /%EF%AC%81?foo=bar&bz=%AC%81
  • This is a unicode character, which can't be decoded from
    ascii. Jinja templates will handle this if it's unicode, or if it's
    hex encoded ascii.
  • The querystring was being quoted, which is incorrect, as:
    1. the special characters in the query string mean something
    2. The rest of the querystring is already quoted. This makes it
      double quoted, as seen in the datastore file
  • We don't want to unquote urls before putting them in the template
    anyway.
    The solution here is to make sure it's unicode passed into the
    function.

Features:

  • includes tests covering changes
  • includes updated documentation
  • includes user-visible changes
  • includes API changes
  • includes bugfix for possible backport (backport already applied)

Please [X] all the boxes above that apply

* url in question /%EF%AC%81?foo=bar&bz=%AC%81
* This is a unicode character, which can't be decoded from
ascii. Jinja templates will handle this if it's unicode, or if it's
hex encoded ascii, but can't take a non-unicode string in python 2 and
put this in a template.
* The querystring was being quoted, which is incorrect, as:
  1) the special characters in the query string mean something
  2) The rest of the querystring is already quoted. This makes it
  double quoted, as seen in the datastore file
* We don't want to unquote urls before putting them in the template
anyway.
* There was s further error passing this unicode path to the template
resolution, where in posix path, it fails:
```
File '/usr/lib/ckan/default/lib/python2.7/posixpath.py', line 73 in join
  path += '/' + b
UnicodeDecodeError: 'ascii' codec can't decode byte 0xef in position 1: ordinal not in range(128)
```
The solution here is to make sure it's unicode passed into the
function.
