#17111 closed Bug (fixed)

simple redirect_to: handle query strings with percent symbols

If you use django.views.generic.simple.redirect_to with query_string=True and the query string contains a % character followed a valid Python conversion character it will cause a TypeError later when url % kwargs is performed. This is particularly easy to encounter when your content includes things like UTF-8 escaped content as the leading %C3 will trigger reliably trigger a TypeError.

Thanks for the fix, acdha. I set up redirect_to earlier today, was getting errors immediately from users, and am happy to see a quick fix!

Seems the class-based generic view suffered from the same problem. Fix happens in #16842.
