Duplicate URL unfurling encoding problem

The "Test messages" forum is not open to guests so it cannot be read arbitrarily by a HTTP client (the unfurling system fetches metadata via an anonymous HTTP request, even if it's an internal link) hence the 403 error.

I've moved the thread (temporarily) to the Off-topic forum so it should unfurl correctly:
From this you should also see that any encoding issues should be resolved already for the next beta.
