Yeah, I screwed that up. I should have gone the other way 'cause it's at the bottom of a range (unlike all the other unassigned chars). Attached are the same tests with s/37f/384/. Could you chop off after the "AZaz" and see if that works and do a binary search to see what it's complaining about?

I18N folks, could you tell me why an NFC validator is objecting to this (beautiful) IRI and if there's some validator I can use for testing:?

The goal is to test as much as possible the valid input to <http://www.w3.org/TR/turtle/#grammar-production-PrefixedName>. In turtle, the localName gets appended to the namespace, hence the url above. The

  [163s] PN_CHARS_BASE ::=    [A-Z] | [a-z] | [#x00C0-#x00D6] | [#x00D8-#x00F6] | [#x00F8-#x02FF] | [#x0370-#x037D] | [#x037F-#x1FFF] | [#x200C-#x200D] | [#x2070-#x218F] | [#x2C00-#x2FEF] | [#x3001-#xD7FF] | [#xF900-#xFDCF] | [#xFDF0-#xFFFD] | [#x10000-#xEFFFF]

production is taken from <http://www.w3.org/TR/REC-xml/#NT-NameStartChar>:
