Redirect to a url that includes square brackets []

[jeffpaul]

Describe the bug
We received the following from @tbenyon on WordPress.ORG:

When saving square brackets in the Redirect To field they get html encoded.
For example, this:
/blog/?categories[]=*
. . . get turned into this:
/blog/?categories%5B%5D=*

This redirect does not work as wanted. This happens with REGEX enabled or disabled.

I’ve tried escaping the brackets with \ but that didn’t work.

Thanks,

Tom

Additional context

[trainoasis]

we have the same issue by using regex to match /. Escaping with \/ does not work. So basically Regex not working properly. Any workarounds? We are trying regex only because of the WPML related issue: #153. Using regex would be a useful workaround, but unfortunately without using slashes not very useful. Do let me know if I can help

It works anyway despite the square brackets get URL encoded. The data is available in the script. @jeffpaul Do we need to fix the visual representation of the parameters then?

[jeffpaul]

@jayedul could be worth fixing the visual representation as long as that doesn't impact functionality negatively
