Abstract
This memo defines a portion of the Management Information Base (MIB) for use with network management protocols in the Internet community. This IANA Charset MIB is [intended to become] an IANA registry. In particular, a single textual convention 'IANACharset' is defined that may be used to specify charset labels in MIB objects. 'IANACharset' was extracted from Printer MIB v2 (work-in-progress). 'IANACharset' was originally defined (and mis-named) as 'CodedCharSet' in Printer MIB v1 (RFC 1759). A tool has been written in C to regenerate this IANA Charset MIB, when future charsets are registered by IANA according to RFC 2978.
This IANA Charset MIB [CHARMIB] module defines the single textual convention 'IANACharset'. Once adopted, all future versions of the IANA Charset MIB [CHARMIB] may 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 (or any other machine-generation method).
It is strongly recommended that future updates to the IANA Charset MIB [CHARMIB] be machine generated (rather than hand-edited) to avoid asynchrony between the IANA Charset Registry [CHARSET] and the IANA Charset MIB [CHARMIB].
Note: Usage questions and comments on this IANA Charset MIB [CHARMIB] should be sent directly to the editor (imcdonald@sharplabs.com).
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].
See section 2 'The Internet Standard Management Framework' of [RFC2570].
Intellectual Property: The C language utility 'ianachar.c' [IANACHAR] is hereby donated by the author (Ira McDonald) to IANA, in perpetuity, free of license or any other restraint.
The [IANACHAR] utility may be used to generate an updated version of the 'IANACharset' 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' (that
contains the IANA-assigned enum label). If 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_ alpha/numeric characters from the 'Name' field
to the enum label (ignoring punctuation, whitespace, etc.).

DESCRIPTION "This MIB module defines the IANACharset Textual
Convention. The IANACharset TC is used to specify
the encoding of string objects defined in a MIB.
Note: The IANACharset TC, originally defined in
RFC 1759, was inaccurately named CodedCharSet.
Note: Best practice is to define new MIB string
objects with invariant UTF-8 (RFC 2279) syntax
using the SnmpAdminString TC (defined in RFC 2571)
in accordance with IETF Policy on Character Sets and
Languages (RFC 2277)."

DESCRIPTION
"Specifies an IANA registered 'charset' - coded character set
(CCS) plus optional character encoding scheme (CES) - terms
defined in 'IANA Charset Registration Procedures' (RFC 2978).
Objects of this syntax are used to specify the encoding for
string objects defined in one or more MIBs. For example, the
prtLocalizationCharacterSet, prtInterpreterDefaultCharSetIn, and
prtInterpreterDefaultCharSetOut objects defined in Printer MIB.
The current list of 'charset' names and enumerated values
is contained in the IANA Character Set Registry at:
http://www.iana.org/assignments/character-sets
Enum names are derived from the IANA Charset Registry 'Alias'
fields that begin with 'cs' (for character set).
Enum values are derived from the parallel 'MIBenum' fields."

IANA should assign a base arc in the 'mgmt' (standards track) OID tree for the 'ianaCharset' MODULE-IDENTITY defined in the IANA Charset MIB [CHARMIB].
Whenever any 'charset' is added to the plaintext IANA Charset Registry [CHARSET], a new version of the IANA Charset MIB [CHARMIB] may be machine-generated with the C language utility [IANACHAR] described in section 3 of this document.
The IANA Charset MIB [CHARMIB] defines the 'IANACharset' 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 [RFC1759] 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 [CHARMIB] supports implementation of the best practices specified 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 [CHARMIB] supports locale-specific MIB objects with variable character sets.
There are no management objects defined in this IANA Charset MIB [CHARMIB]. Only one textual convention (IANACharset) is defined.
The editor would like to thank: Bert Wijnen (Lucent) for his original suggestion that the 'IANACharset' textual convention should be extracted from Printer MIB v2 (work-in-progress) [RFC1759bis]; Ron Bergman (Hitachi Printing Solutions) and Harry Lewis (IBM) for their many years of effort as editors of Printer MIB v2 (work-in-progress) [RFC1759bis].
