IDN KeywordsPermissible Code PointsNon ASCII TLDsRegistrar Selection ProcessUDRP Review The Permissible Code Point Issue By 'permissible code point' issues, we refer to the problems that might arise from the use of certain non-ASCII characters included in the Unicode Standard within IDN domain name labels. At present, the DNS host name specifications limit permissible code points in domain name labels to a restricted subset of 7-bit ASCII.In addition to the characters of every language that could be identified and standardized by the Unicode Consortium, the Unicode Standard contains several sets of "characters" that do not, in fact, appear in any conventional human language. The Permissible Code Point Issue (2) The IDN Committee has communicated a recommendation to the IETF that it should proceed conservatively, using an "inclusion-based" approach to the definition of "Internationalized Hostnames", so as to leave out C at least temporarily C the sets of potentially problematic characters, most notably: - line and symbol-drawing characters;

- symbols and icons that are neither alphabetic nor ideographic language characters, such as typographical dingbats;

- punctuation characters;

and - spacing characters.These comments were submitted for IESG review IETF (IESG) approval of Internet-Drafts, Oct. 24,
