Question

\Hi All,

A user is entering a unicode value (u’\u2206′) into a text box that is submitted to my django view. The view uses the GET data to generate a URL to get back to the search page later.

It’s having trouble generating the URL when the user submits a unicode charactor.

What is the best practice here. Should I encode the get data before sending it into urlencode? What encoding should I use?

Relevant code:

search_form = SearchForm(request.GET)
get_data = dict([(key,item) for (key,item) in search_form.data.items()])
get_params = '&' + urllib.urlencode(query=get_data.items())

Error:
Traceback (most recent call last):

  File "/opt/python/lib/python2.7/site-packages/django/core/handlers/base.py", line 100, in get_response
    response = callback(request, *callback_args, **callback_kwargs)

    get_params = '&' + urllib.urlencode(query=get_data.items())

    v = quote_plus(str(v))

UnicodeEncodeError: 'ascii' codec can't encode character u'\u2206' in position 15: ordinal not in range(128)

Answer 1

Encode as UTF-8 before URL-encoding.
