Filtering from charts with non-ASCII characters are passed without modification to the IE URL, which then fails. In Chrome the non-ASCII characters are converted with %.
Filtering the same names in the side table filter works fine, django sorts out the %.
It's likely we need to use django.utils.http.urlquote or something. https://docs.djangoproject.com/en/1.8/ref/utils/#module-django.utils.http
from django.utils import http
http.urlquote("Ländryggen DX")
u'L%C3%A4ndryggen%20DX'
Is this something you might look at @dplatten?
Initial bug report was from Love Kull
Hi @edmcdonagh. I'll take a look. It might be https://docs.djangoproject.com/en/1.8/ref/utils/#django.utils.encoding.iri_to_uri that is needed, according to http://twigstechtips.blogspot.co.uk/2013/06/pythondjango-dealing-with-utf8-in.html.
