It  is one label that is a mixture of RTL end LTR chars. It is invalid 
of course.
I've noted that not all browsers answer it is invalid.
Here are the tests (http://www.w3c.org.ma/Tests/IDNs/Issue2.html)

In fact, in a mail I sent before, it was question about:
- Arabic & Hebrew IDNs that are not displayed as claimed by Firefox. 
.museum TLD is trusted (Firefox displays IDNs in native) but in punycode 
for Arabic & Hebrew. (http://www.w3c.org.ma/Tests/IDNs/Issue1.html)
- IDNs with %xx in links (http://www.w3c.org.ma/Tests/IDNs/Issue3.html)
Browsers accept links (href attribute) with IDNs in native and punycode 
but not in escaped notation.
Are %xx encoding a valide notation  for IDNs?

Regards, Najib
