"Invalid non-printable ASCII character in URL" since 0.24.0

[vphpersson]

Starting from version 0.24.0, I am no longer able to use \x1f in URLs. The exception I'm now seeing is raised from here:

# If a URL includes any ASCII control characters including \t, \r, \n,
# then treat it as invalid.
if any(char.isascii() and not char.isprintable() for char in url):
    raise InvalidURL("Invalid non-printable ASCII character in URL")

Is there a particular reason for not allowing non-printable ASCII characters anymore?

I see. I haven't looked at the code for the previous version, but I assume characters such as \x1f were percent-encoded if provided. With the current version, I now have to do that myself?

tested your assumption and yep.
