Fed Wiki Unicode Domain bug

Raised because it appears as though Fed Wiki can't link to UTF8 Domains.

When I drag a link to λ.matthew.nz, I expect to see a synopsis of the page that I'm dragging in.

What I see instead is no interface feedback and errors in console about connecting to that domain.

Investigated if this was related to basicauth by toggling it off and it did not appear to fix it.

## TODO - [ ] File a bug with reproduction steps - [ ] Patch - [ ] Remove FIXME from ./etc/Caddyfile - [ ] Link λ.matthew.nz from Projects
