I have a goal tracking clics on an external link which downloads a file. The filenames can have special characters like "spaces".
The goal is set with the encoded URL copied directly from the site like "my%20file%20link.pdf". With this encoded filename, the goal is never converted. With the non-encoded filename like "my file link.pdf", it's converted.
Maybe Piwik should handle this use case and convert goals even with encoded URLs.
No. Apache/PHP already does a decode for %xx. If we do another decode, we make it harder to specify literal %xx. It could also inadvertently provide hackers with a method to bypass filters like mod_security.
Let's try to reproduce to see if this bug still applies.
