C. Technical - Justification
1. Has this proposal for addition of character(s) been submitted before? This proposal on these 6 symbols has notbeen submitted to WG2 before. In the 18th Ideographic Rapporteur Group (IRG) meeting, IRG
recommends Hong Kong Special Administrative Region to submit these 6 symbols to WG2. The
resolution of that meeting is shown in Annex B.
If YES explain

Yes
If YES, with whom? (a) Chinese Language Interface Advisory Committee (CLIAC **).
(b) Public consultation in Hong Kong, including members of the public and ITvendors.
( ** CLIAC was set up in 1999 by the ITSD of HKSARG to provide advice on theestablishment of a common Chinese language interface for facilitating more effective
electronic communication using Chinese by the public in Hong Kong. Details of CLIAC
can be found in http://www.info.gov.hk/digital21/eng/structure/cliac.html)《香港增補字符集》的公佈 中諮文件編號

http://www.info.gov.hk/digital21/chi/structure/download/cl0899.zip (Chinese version only).
3. Information on the user community for the proposed characters (for example:
size, demographics, information technology use, or publishing use) is included?
Yes
Reference: Font and input software for HKSCS-2001 are downloaded about 20,000 times by the public of
the Hong Kong monthly.
4. The context of use for the proposed characters (type of use; common or rare)
CommonReference:Yes

5. Are the proposed characters in current use by the user community?
If YES, where? Reference:
Microsoft ‘s HKSCS-2001 Support for Windows Platforms (www.microsoft.com/hk/hkscs),

most Chinese font products ( e.g. www.dynalab.com.hk/free/dynafont/hkscs/hkscs.zip, ) andmost Chinese input methods programs (e.g. products section at www.penpower.com.hk ).
6. After giving due considerations to the principles in Principles and Procedures document (a WG 2 standingdocument) must the proposed characters be entirely in the BMP?
If YES, is a rationale provided?
If YES, reference:
7. Should the proposed characters be kept together in a contiguous range (rather than being scattered)?
8. Can any of the proposed characters be considered a presentation form of an existing
character or character sequence?
If YES, is a rationale for its inclusion provided?
If YES, reference:
9. Can any of the proposed characters be encoded using a composed character sequence of either
existing characters or other proposed characters?
If YES, is a rationale for its inclusion provided?
If YES, reference:
10. Can any of the proposed character(s) be considered to be similar (in appearanceor function) to an existing character?

If YES, reference:
Is a list of composite sequences and their corresponding glyph images (graphic symbols)
provided?

The national body or liaison organization (or any other organization or an individual) proposing newcharacter(s) or a new script shall provide:1.
Proposed category for the script or character(s), character name(s), and description of usage.
2.
Justification for the category and name(s).
3.
A representative glyph(s) image on paper:
If the proposed glyph image is similar to a glyph image of a previously encoded ISO/IEC 10646
character, then additional justification for encoding the new character shall be provided.
Note: Any proposal that suggests that one or more of such variant forms is actually a distinct character
requiring separate encoding, should provide detailed, printed evidence that there is actual, contrastive use of
the variant form(s). It is insufficient for a proposal to claim a requirement to encode as characters in theStandard, glyphic forms which happen to occur in another character encoding that did not follow theCharacter-Glyph Model that guides the choice of appropriate characters for encoding in ISO/IEC 10646.
Note: WG 2 has resolved in Resolution M38.12 not to add any more Arabic presentation forms to thestandard and suggests users to employ appropriate input methods, rendering and font technologies to meetthe user requirements.

Mappings to accepted sources, for example, other standards, dictionaries, accessible publishedmaterials
Computerized/camera-ready font:Prior to the preparation of the final text of the next amendment or version of the standard asuitable computerized font (camera-ready font) will be needed. Camera-ready copy is mandatory
for final text of any pDAMs before the next revision. Ordered preference of the fonts is True Typeor PostScript format. The minimum design resolution for the font is 96 by 96 dots matrix, forpresentation at or near 22 points in print size.
List of all the parties consulted.
Equivalent glyph images:
If the submission intends using composite sequences of proposed or existing combining and noncombining characters, a list consisting of each composite sequence and its corresponding glyph
image shall be provided to better understand the intended use.
Compatibility equivalents:
If the submission includes compatibility ideographic characters, identify the equivalent unified CJK
Ideograph character(s).
Any additional information that will assist in correct understanding of the different characteristics
and linguistic processing of the proposed character(s) or script.
