Abstract This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. In particular, it defines a single textual convention 'CodedCharSet' that may be used to specify charset labels in MIB objects, for example 'prtLocalizationCharacterSet' in Printer MIB v2 (RFC nnnn). 'CodedCharSet' was originally defined in Printer MIB v1 (RFC 1759). McDonald Expires 5 February 2003 [Page 1]

Internet Draft IANA Charset MIB 5 August 2002 1. Introduction This IANA Charset MIB module defines the single textual convention 'CodedCharSet'. Once adopted, all future versions of the IANA Charset MIB will be machine-generated, whenever the IANA Charset Registry [CHARSET] is updated by IANA staff according to the procedures defined in [RFC2978], using the utility [IANACHAR] described in section 3 of this document. 1.1. Conformance Terminology The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119]. 2. SNMP Network Management Framework See section 2 'The Internet Standard Management Framework' of [RFC2570]. McDonald Expires 5 February 2003 [Page 3]
Internet Draft IANA Charset MIB 5 August 2002 3. Generation of IANA Charset MIB The C language utility 'ianachar.c' [IANACHAR] will generate an updated version of the 'CodedCharSet' textual convention by reading and parsing the plaintext IANA Charset Registry [CHARSET]. This utility parses each charset registration, finding (in order): 1) The 'Name' field (which is saved for a fallback - see below); 2) The 'MIBenum' field (which contains the IANA-assigned positive decimal enum value); and 3) The (usually present) 'Alias' field that begins with 'cs' (which contains the IANA-assigned enum label). If such an 'Alias' field is not found, the utility constructs one from the 'Name' field by: - Beginning the enum label with a lowercase 'cs' prefix; - Copying _only_ the numeric and alpha characters from the 'Name' field to the enum label (ignoring all punctuation, whitespace, etc.). The [IANACHAR] utility is hereby donated by the author (Ira McDonald) to IANA, in perpetuity, free of license or any other restraint. McDonald Expires 5 February 2003 [Page 4]

Internet Draft IANA Charset MIB 5 August 2002 5. IANA Considerations IANA should assign a base arc in the 'mgmt' (standards track) OID tree for the 'ianaCharset' MODULE-IDENTITY defined in the IANA Charset MIB. Each new version of the IANA Charset MIB should be machine-generated with the C language utility [IANACHAR] described in section 3 of this document and posted at [CHARMIB], whenever any 'charset' is added to the plaintext IANA Charset Registry [CHARSET]. 6. Internationalization Considerations The IANA Charset MIB defines the 'CodedCharSet' textual convention that may be used in a given MIB module to supply explicit character set labels for one or more text string objects defined in that MIB module. For example, the Printer MIB v2 [RFCnnnn] defines the three character set label objects 'prtLocalizationCharacterSet' (for description and console strings), 'prtInterpreterDefaultCharSetIn' (for received print job input data), and 'prtIntpreterDefaultCharSetOut' (for processed print job output data). The IANA Charset MIB supports implementation of the best practices defined in "IETF Policy on Character Sets and Languages" [RFC2277]. Note: The use of the 'SnmpAdminString' textual convention [RFC2571], which has a fixed character set of UTF-8 [RFC2779], is strongly encouraged in defining new MIB modules. The IANA Charset MIB supports locale-specific MIB objects with variable character sets. 7. Security Considerations There are no management objects defined in this IANA Charset MIB. 8. Acknowledgements The editor would like to thank: Bert Wijnen (Lucent) for his original suggestion that the 'CodedCharSet' textual convention should be exported from Printer MIB v2 [RFCnnnn]; Ron Bergman (Hitachi Koki) for his many years of effort on Printer MIB v2 [RFCnnnnn]; and Tom Hastings (Xerox) for originally introducing the 'CodedCharSet' textual convention into Printer MIB v1 [RFC1759].
