The UK fed metadata has a bug in it:
<OrganizationDisplayName xml:lang="en">Bournville College of Further Education
(that is to say a line feed and spaces after the name). This is of course correct XML (just not what the user wanted).
The Disco feed spits this out:
"value": "Bournville College of Further Education
IE and FF can eat this, but Chrome and Safari cannot. If I read http://www.ietf.org/rfc/rfc4627.txt correctly, <cr><lf> needs to be escaped - although I suspect that the user would prefer to have it stripped....
FWIW, testing is in the early stages, but unicode seems to be OK...
