> We recently upgraded to 0.9.2 from 0.8.2 or so. One of our topologies had a percent encoded value in the id 'destination%F5backfill' (or interpreted 'destination_backfill'). The UI is unable to view this topology giving us the error,

> So it seems the UI is translating the percent encoded value which causes this issue. We shouldn't be putting these values in our topologies id in the first place but thought I would log this to see if you wanted to try to limit what characters are allowed in a topology id.
