Tick in URL not compatible with Tweetdeck

[RichardTaylor]

Alaveteli sometimes puts the following in the URL for a search result.

utf8=✓

This resulted in Tweetdeck not properly counting the characters used in a tweet including a URL containing the tick.

This may be a bug in Tweetdeck, but perhaps doing unusual things isn't a good idea.

It appears utf8=✓ is added to the URL when a search is conducted from the second search box on a public body page, the search box under "Keywords"

It isn't something we've added, it comes from Rails. https://github.com/rails/rails/blob/4866154/actionview/lib/action_view/helpers/form_tag_helper.rb#L816-L823. This gives some background as to why http://intertwingly.net/blog/2010/07/29/Rails-and-Snowmen

The issue will be resolved when we #5159 as the new action_controller.default_enforce_utf8 config defaults to false. See: rails/rails#32125

I would say it is a fairly standard thing to do and we won't do anything for this other than upgrading Rails so am going to close this issue.

I hit this issue again today.

Workarounds include removing the utf8=✓ parameter from the URL or escaping it to utf8=%E2%9C%93

Assume we might actually need #5851 since #5159 has already been merged.
