Information accompanying submissions

The process of deciding which characters should be included in the repertoire of the standard by WG 2 depends on the availability of accurate and comprehensive information about any proposed additions. WG 2, at its San Francisco meeting 26, designed a form (template) that will assist the submitters in gathering and providing the relevant information, and will assist WG 2 in making more informed decisions.

This form is part of the WG 2 Principles and Procedures document and is available on line at http://std.dkuug.dk/JTC1/SC2/WG2/docs/summaryform.html.

A duly completed proposal summary form must accompany each new submission. The latest version of this form must be used in submissions. Such a form will assist WG 2 to better evaluate the proposal, and progress the proposal towards a speedier acceptance and inclusion in the standard. Submitters are also requested to ensure that a proposed character does not already exist in the standard.

Submitters are encouraged to visit the "Where is my Character" page on the Unicode web site for more information on checking if their proposed character or script is already encoded in the standard, or a similar proposal has already been made by someone else. There are also several electronic discussion lists maintained by the Unicode consortium that one could use to discuss with other experts internationally on various subjects related to the standard. Submitters are also encouraged to familiarize themselves with ISO/IEC TR15285 - Character Glyph Model. The latest version of ISO/IEC 10646 as well as ISO/IEC TR15285 are available on line under 'Freely Available Standards' at: http://standards.iso.org/ittf/PubliclyAvailableStandards/.

National bodies should take note of the guidelines in section C.4 Some guidelines on proposing new material as ballot comments in the P&P document.

In addition to text extracted from the standard in Annex L: Character-naming guidelines in the P&P document, the following definitions from the standard are also referenced in the proposal summary form:

Clause 4.12 Combining character:
A member of an identified subset of the coded character set of ISO/IEC 10646 intended for combination with the preceding non-combining graphic character, or with a sequence of combining characters preceded by a non-combining character (see also 4.14).
NOTE - ISO/IEC 10646 specifies several subset collections which include combining characters.

Clause 4.14 Composite sequence:
A sequence of graphic characters consisting of a non-combining character followed by one or more combining characters (see also 4.12).
NOTE 1 - A graphic symbol for a composite sequence generally consists of the combination of the graphic symbols of each character in the sequence.
NOTE 2 - A composite sequence is not a character and therefore is not a member of the repertoire of ISO/IEC 10646.

Submitter's responsibilities

The national body or liaison organization (or any other organization or an individual) proposing new character(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 the Standard, glyphic forms which happen to occur in another character encoding that did not follow the Character-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 the standard and suggests users to employ appropriate input methods, rendering and font technologies to meet the user requirements.
  4. Mappings to accepted sources, for example, other standards, dictionaries, accessible published materials.
  5. Font resource:
    A font must be provided to the Editor promptly after the characters have been approved by WG2 for use in printing the charts. If a font is not provided, the Editor cannot include the glyphs in the charts and, as a result, the repertoire of characters corresponding to these glyphs will not be included in draft amendments. Fonts must be in one of the following formats (in preferential order): OpenType, TrueType, Postscript Type 1.
    Fonts submitted must have no license restrictions that prevent embedding into PDF documents. Because of synchronization between ISO/IEC10646 and The Unicode Standard, any grant of license must cover use in publishing both standards and related documents (see resolution M45.30). For technical reasons, the editors must be able under that license to freely modify or replace glyph outlines in their copies of the fonts. The submitter should be prepared to provide fonts of suitable quality and license conditions, unless equivalent fonts are already available to the editors.
  6. List of all the parties consulted: Towards ensuring that all significant stakeholders have been consulted, WG 2 requests that submitters solicit feedback from other groups who use the proposed characters, and list these contacts. Submitters are encouraged to provide the email id-s of the submitters as well as other experts who have been consulted to facilitate any clarification queries.
  7. Equivalent glyph images:
    If the submission intends using composite sequences of proposed or existing combining and non-combining characters, a list consisting of each composite sequence and its corresponding glyph image shall be provided to better understand the intended use.
  8. Compatibility equivalents:
    If the submission includes compatibility ideographic characters, identify (per resolution M45.29):
  9. Properties that may affect the BiDi processing
    Any BiDirectional algorithm related properties associate with the characters should be spelled out (see UAX#9 - http://www.unicode.org/reports/tr9/).
  10. Any additional information that will assist in correct understanding of the different characteristics and linguistic processing of the proposed character(s) or script.
  11. If any of the proposed characters are suitable as syntax characters please take note of guideline D.2.5 in the P&P document and of Unicode Standard Annex 31 at http://www.unicode.org/reports/tr31/.
  12. If the proposal is for a new script, identify the standardized characters that are commonly used directly in the script, or proposed to be unified with the characters of the script, in particular standardized characters allocated in different blocks. Examples include punctuation marks and combining marks. Such information will assist in assigning properties for characters shared across multiple scripts or in identifying character repertoires needed to support particular languages.
  13. If you are aware of already standardized characters that are visually close to any of the proposed characters, you are invited to list them in the proposal. This will assist in the analysis of the script for 'visually confusables', towards providing additional guidance on use of the standard from a security perspective (see UTR#36 - Unicode Security Considerations - at http://www.unicode.org/reports/tr36/).
