Filter Query String does not unescape

[danieljimenez]

The filter query string does not unescape, so when used with Slack, the search breaks.

For example, this should work: https://ec2instances.info/?filter=(m5%7Cr4).2xlarge&cost_duration=monthly

This works: https://ec2instances.info/?filter=(m5|r4).2xlarge&cost_duration=monthly

However Slack correctly converts the | to %7C, breaking the above link. AlfredApp does the same thing when using the filter for a URL searcher.

TIA! DJ
