Amaya again failing for IRIs?

Dear Amaya Team,

There is a long-standing IRI test at
http://www.w3.org/2001/08/iri-test/resumeHtmlImgSrcBase.html.
I very well remember that this test worked on earlier versions
of Amaya (in particular in version 8.2+, and many before),
but it doesn't work anymore on 8.5 for Windows.

Can you please fix it? Many thanks,    Martin.
