I see that Django's urlencode filter doesn't encode slash by default:

https://docs.djangoproject.com/en/dev/ref/templates/builtins/?from=olddocs#urlencode

I know I can make it encode the slash, but why doesn't it do it by default? Isn't it accepted behavior to encode the slash, given that it's a reserved character in URLs?

python django url urlencode
