Application of Charset Registration
Purpose
This is a proposal to register "Big5-HKSCS" as a Charset name with
Internet Assigned Numbers Authority (IANA).
Background
2. To facilitate electronic communication in the Hong Kong
Special Administrative Region (SAR), the Hong Kong Supplementary
Character Set (HKSCS), a supplement to the standard character set of
Big-5, was developed in 1999. This supplementary character set
includes characters collected from various sectors in Hong Kong and
represents a common set for the community. It has been widely used in
Hong Kong.
3. HKSCS specifies two coding schemes -- one is the extension to
the Big-5 coding scheme and the other one is an extension to the ISO
10646 standard.
4. This registration request is specifically made for the Big-5
extension since proper registration will facilitate development of
Internet-related software supporting HKSCS.
Registration Requirements (as defined in RFC 2278)
5. Required characteristics
- The proposed charset conforms to the definition of a "charset"
as defined in 2.4 of RFC 2278.
- The proposed charset is suitable for use in MIME.
- The proposed charset is specified in a stable, openly
available specification.
6. New charsets
- The proposed charset is NOT a new charset.
7. Naming requirements
- Proposed name for the charset is "Big5-HKSCS".
- The name conforms to the ABNF definition in sect 3.3 of RFC
2278.
8. Functionality requirement
- The proposed charset functions as an actual charset.
9. Usage and implementation requirements
- The proposed charset has been widely adopted by the market,
the public and the Government. This is the standard supplementary
character set used for information exchange in Chinese between the
public and the Hong Kong SAR Government.
10. Publication requirements
- The proposed charset has been published by the Hong Kong SAR
Government since 1999.
- An online copy of the Hong Kong Supplementary Character Set
can be viewed at
<http://www.info.gov.hk/digital21/eng/hkscs/download/e_hkscs.pdf>
11. MIBenum requirements
- A MIBenum value for the proposed charset will be assigned by
IANA at the time of registration.
