title: After Starting to use Google Funding Choices, site is handing out a weird "FCCDCF" cookie that breaks other sites
body: <p>For advertising consent management we're looking at starting to use Google Funding Choices, but have found that the Funding Choices tag results in a weird cookie named &quot;FCCDCF&quot; being handed to the browser (on a test instance of our site - this hasn't gone live yet). The cookie data is somewhat odd too, possibly malformed:  <code>[&quot;AKsRol-_Joh_37zZXODIWUr6g9_v3puYlD6kBYC50uYqE-PvJ2hCRtV9GY9Zbx4u1bqRt-Z5u2FjQYF209zdntY0tJfDYlxi9WEjlTgf-o3B2Cc0xt-gYmh0G7zv3Ra7uJDxyz5-tN8tUXNCNef1cgm15_iL6dkS1A==&quot;],null,[&quot;[[],[],[],[],null,null,true]&quot;,1597688653715]]</code></p>
  <p>This cookie is causing some other (live) sites of ours to fail with 500 errors.
  I'm thinking that because of the embedded quotes and other nonalphanumeric symbols it's screwing up some cookie-reading code.  I have found virtually nothing about this issue online and nothing in the Funding Choices API docs. The closest thing to a mention of it is some cookie tracking sites that list it in ways that suggest it's spammy/scammy.</p>
  <p>What's going on here? Anybody else using Google Ad Manager and Funding Choices and seeing this?
  I could add some code to delete it, but I'm wondering if it is something Funding Choices is expecting to see. But if so <strong>why is it so problematic to other code?</strong> Seems like a big fail on Google's part.</p>
