Inclusion of New Characters in the HKSCS

The Government recognizes the need for the public and government departments to include new characters into the Hong Kong Supplementary Character Set (HKSCS) from time to time. In collaboration with the Chinese Language Interface Advisory Committee (CLIAC), the Government published the procedures and principles for inclusion of new characters in the HKSCS in April 2000 and also revised the principles for inclusion of new characters in the HKSCS in September 2009.

The CLIAC will meet regularly to consider applications for inclusion of characters in the HKSCS. Once approved, the new HKSCS characters will be submitted to the International Organization for Standardization (ISO) for inclusion in the future releases of the ISO 10646 standard.

Procedures for the Inclusion of Characters in the HKSCS

1. The public and government departments may submit their applications for inclusion of characters in the HKSCS to the Secretariat of the CLIAC. The application should include the glyph, meaning and pronunciation of the characters, and also preferably the usage explanation, origin and sample sentences in relation to the characters.

2. On receipt of an application submitted by the public, the Secretariat of the CLIAC will pass the application to the Working Group on Characters for Chinese Computer Systems (Working Group) for examination. Applications submitted by government departments will initially be considered by an internal special duty group before being forwarded to the Working Group for examination. The Working Group will examine the applications.

3. The Working Group will examine the applications according to the principles for the inclusion of characters as listed below. The public and government departments should refer to these principles beforehand so as to avoid making unnecessary applications, prevent the waste of resources and help speeding up the application process.

4. Applications having passed the examination of the Working Group will be submitted to the CLIAC for approval. The assigned internal codes, glyphs and related information of the approved characters will be published on the Internet. However, such information in respect of the approved characters is for reference only. The approved characters will officially become part of the HKSCS at a later stage (see Paragraph 6 below).

5. An unsuccessful application may be reconsidered by the Working Group upon request by the applicant and upon the applicant supplying further details in respect of the characters in the application.

A list of characters not accepted for inclusion in the HKSCS (from 31.3.2008 onwards) is available for your reference. (pdf, 118 KB)

As many of these characters are assigned with ISO/IEC 10646 code points, users can handle these characters on platforms supporting ISO/IEC 10646 or Unicode.

Official Revision of the Hong Kong Supplementary Character Set

6. The development of products by software developers to support new HKSCS characters takes time. Moreover, frequent updates to the HKSCS will cause inconvenience and even chaos to users. Therefore, the Working Group will consider the practical timing in respect of the official inclusion of the newly approved characters into the HKSCS, and make recommendation to the CLIAC for the official announcement of revisions to the HKSCS.

7. All newly approved HKSCS characters that are not yet included in the ISO 10646 standard will be submitted to the Ideographic Rapporteur Group (IRG) of the International Organization for Standardization (ISO).

8. To better align with the ISO/IEC 10646 international standard, the Chinese Language Interface Advisory Committee (CLIAC) has decided that, with effect from September 2009, the Hong Kong Supplementary Character Set (HKSCS) will only adopt the official code points assigned by the ISO upon its inclusion of proposed HKSCS characters in the international coding standard. The CLIAC has further decided that, to avoid double code assignment, no HKSCS 'standard internal codes' will be given to the HKSCS characters newly accepted by the ISO. The 'standard internal codes' assigned to previously published HKSCS characters remain valid.

Results of the Inclusion of Characters in the HKSCS

1. The procedures for inclusion of Characters in the HKSCS were published in April 2000. The public and government departments could submit their applications for inclusion of characters in the HKSCS to the Secretariat of the CLIAC. The assigned internal codes, glyphs and related information of the approved characters will be published on this web page.

2. Information of the approved characters including their assigned internal codes and glyphs is for reference only. In practical timing, the CLIAC would release the next revision of the HKSCS which includes the approved characters.

Number of characters approved since publication of HKSCS-2004: 68
