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:? <http://a.example/AZazÀÖØöø˿Ͱͽ΄῾⁰↉Ⰰ⿕、ퟻ豈ﷇﷰ�𐀀󠇯> 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>: [4] NameStartChar ::= ":" | [A-Z] | "_" | [a-z] | [#xC0-#xD6] | [#xD8-#xF6] | [#xF8-#x2FF] | [#x370-#x37D] | [#x37F-#x1FFF] | [#x200C-#x200D] | [#x2070-#x218F] | [#x2C00-#x2FEF] | [#x3001-#xD7FF] | [#xF900-#xFDCF] | [#xFDF0-#xFFFD] | [#x10000-#xEFFFF] > Removing it (Greek question mark), I then get: > > WARN [line: 2, col: 43] Bad IRI: > <http://a.example/AZaz???????????????????????> Code: 46/NOT_NFC in > PATH: The IRI is not in Unicode Normal Form C. > WARN [line: 2, col: 43] Bad IRI: > <http://a.example/AZaz???????????????????????> Code: 47/NOT_NFKC in > PATH: The IRI is not in Unicode Normal Form KC. > WARN [line: 2, col: 43] Bad IRI: > <http://a.example/AZaz???????????????????????> Code: > 56/COMPATIBILITY_CHARACTER in PATH: TODO > > with or without the last char. > > >I poked around looking for composing characters in the PN_CHARS_BASE > >character ranges. \u02ff MODIFIER LETTER LOW LEFT ARROW seemed like it > >could be a culprit, but fileformat.info claims it's not in a combining > >class.
