explanation of I18N-ISSUE-190: attempting to erase combining marks?
===============================================================

Issue: Section 6.4. PN_CHARS_BASE erases various Unicode ranges without explanation. This appears to be an attempt to eliminate combining marks and the surrogates?

Turtle's PN_CHARS_BASE
<http://www.w3.org/rdf-clean/rdf-turtle/index.html#grammar-production-PN_CHARS_BASE>
is derivative of XML's NameStartChar
<http://www.w3.org/TR/2008/REC-xml-20081126/#NT-NameStartChar>,
presumably leveraging the wisdom which went into XML
identifiers. Changing this would have very large compatibility impact
on SPARQL, RDF/XML, OWL's XML format, GRDDL, etc. Is there motivation
to change XML?


Please indicate whether this address the stated issue.
