The agenda was revised to incllude: Mailing Lists, E-mail access Indic SC, Korean SC Chair apologizes for late notice: E-Mail 'black hole' D. Consortium Business Status ----------------------------- 1. New Unicode VP Asmus Freytag was promoted from Technical Director to VP of Marketing: this represents a shift in focus of the consortium towards more activities gearde to promotion and adoption of the Unicode Standard. 2. UIW proceedings availability Proceedings from UIW#2 are now available, free distribution possible for member companies for internal use. 3. Volume II status Book status: cover has been decided upon (based on KangXi dictionary) and has been printed. Final camera ready copy to go to Addison next weeks, few weeks to printed book. Han cross mappings are available now, free to consortium members. 4. Review of Marketing activities The consortium intends to announce the availability or announcements of products supporting or incorporating Unicode. Another focus of PR activities will be the Unicode Workshop announcements. 5. Technical Reports Unicode Technical Papers are a new avenue for Unicode to disseminate conclusions from technical discussions in the UTC. They can include authoritative information or recommended solutions. The latter are not excluded from becoming part of the standard at a later point. 6. Volume 1 sales Book Sales: as of 1/1/91 Printed 60000 Sales 2240 US 1600 Special 418 Mail 7 Canada 31 International 88 Translations for the Unicode book: Mark Davis has notified Addison Wesley on our desire to have translations to the following languages: German, Japanese. They have right to first refusal for 90 days. 7. Office Manager The consortium is hiring an Office Manager to manage the head quarters more effectively. E-Mail alias for consortium head-office: unicode-inc@cairo.eng.sun.com, Telephone: 415-961-4189 8. New Membership categories As of 5/1 1992 there are now three categories of membership: full, associate and individual. Document UTC92-16 defines the fees, participitation righrs and benefits for these classes of members. UTC recommends to officers that invited liaisons from other standards groups be granted participitation rights commensurate to associate membership status (accepted by 8:0:0 vote). Question: what will be the status of individual contributors and experts. A: The new membership categories do not preclude inviting these experts Mike Ksar announces that HP intends to join. Darryl Barksdale announces that WordPerfect will rejoin. Glenn Adams announces that Metis intends to join as an associate. E. Upcoming meetings: --------------------- UTC #53 Juli 15 (UIW SC), 16 (SC day), 17 (UTC) Bay Area hosted by Apple UIW #3 August 6,7, Bay area. UTC #54 September 9 (UIW SC), 10 (SC day), 11 (UTC) hosted by Microsoft UTC #55/Membership meeting November 19 (SC), 20 (UTC and membership) hosted by HP UTC#56 February 11 (SC), 12 (UTC) in Provo, Utah, hosted by Novell II. 10646 Merger ================ Need 3/4 majority to pass the DIS 10646-1.2. Countries are voting now until May 29, 1992. Countries can change their vote until the end. Pass/Fail is determined by ISO on basis of simple count. Technically failed standard may sometimes pass by accommodation of one or two negative votes, but this is very difficult. June 29, 1992 SC2/WG2 in Seoul, Korea to define technical content based on votes. To reach a consensus will be difficult, because of contradictory votes by countries. III Subcomittee Status ====================== A. New Scripts SC ----------------- 1. Status Meeting was held an May 1. Status of the big 5 scripts is unchanged. 2. Proposals Dissolve the Indic SC effective 5/9/92 7:0:1 Change the name of New Script SC to Script SC and incorporate the body of work from the Indic SC 8:0:1 B. Indic SC ----------- 1. Status 2. Resolution: The UTC reviewed the Draft Thailand ballot on ISO/IEC DIS 10646-1.2 dated May 7, 1992. The UTC has noticed the requirement to remove 5 THAI characters (U+0E70 - U+0E74) and 5 LAO characters (U+0EF0 - U+0EF4). In the interest of the merger between ISO 10646 and Unicode the UTC authorizes its representatives attending the SC2/WG2 meeting in Korea to be flexible on this subject. In addition the UTC instructs its liaisons to X3L2,CSA and other national standards organizations to convey this Unicode position. (10:0:1) Glenn Adams is authorized by consensus to speak for Unicode in explaining the technical merits for the characters in question. C. Bidi ------- 1. Status: see document UTC92-021 2. Resolution The UTC reviewed the Draft SII ballot on ISO/IEC DIS 10646-1.2 dated May 3, 1992. In the interest of the merger between ISO 10646 and Unicode the UTC supports acceptance of the comments on the Israeli YES vote. More specifically the UTC can accept the following points: 1) Addition of two new BIDI formatting characters: INHIBIT SYMMETRIC SWAPPING (U+206A) ACTIVATE SYMMETRIC SWAPPING (U+206B) The default state is ACTIVATE SYMMETRIC SWAPPING in which characters listed in clause 20 should be interpreted and rendered as OPENING and CLOSE characters. The UTC believes that while this functionality is useful it is better achieved by other, out of band information (as opposed in text stream controls). The UTC encourages SII to consider alternatives. 2) Removal of Annex C which specifies the list of mirrored characters in the bidi context. Alternatively Annex C should be reworded to be applicable only to Arabic script. 3) Modification of the Multiple Combining Characters clause to clarify that Hebrew combining marks have fixed position, determined by the rules of Hebrew script, and do not follow the default stacking behavior. 4) Redefining Hebrew character collections, modification of names, changing the position of Hebrew presentation variants, and other comments not related to Unicode 1.0. This resolution was adopted by UTC.(7:2:1) D. Han SC --------- 1. UniHan Data Base Cleansing of the Han data base from proprietary data is in progress. The DB consists of Macintosh fonts and a hypercard stack. 2. Resolution Dissolve the Korean SC effective 5/9/92 (by consensus) Change the name of Han SC to East Asia SC and have as its scope syllabic and ideographic scripts of East Asia, as well as Hangul (by consensus) 3. Korean proposal The SC reviewed a Korean proposal to change the DIS in the following manner. 1. 3-part style combining Jamos (a) Remove current spacing Jamos (~80) (b) add 3-part non spacing set (<250) 2. Withdraw Umjeols from DIS 1.2 6000 composed syllables) The subcommittee was not in consensus over removal of 2350 KCS6501, but in consensus to forego adding the 4000 Hangul syallables from the DIS not yet in Unicode. 3. Add Kugyol (<250) UTC resolutions: UTC in favor to consider that Kugyol be coded, East Asia SC to work with Korea on defining, reviewing coding.(carried by consensus) Change the combining Jamos from DIS 1.2 to the Korean JTC1/WG2 3- part combining jamo proposal. (by consensus) Unicode considers combining Jamos to be the best technical solution for representing Korean text, and sees no need for precomposed Hangul syllables, EXCEPT for requirements of compatibility. The set of needed compatibility characters include the characters from KSC 5601 plus 270 Hangul syllable from widespread industry standards. UTC would support a proposal from Korea to make these characters as a new Korean Compatibility zone in order to discourage the use of precomposed Hangul syllables and encourage the use of combining jamos UTC supports removing the precomposed Hangul syllables from 10646 not needed for compatibility (8:1:1) UTC recommends that the officers examine the implications, including procedural and legal implications of a move by the UTC to support a Korean proposal to remove ALL precomposed Hangul syllables from Unicode and report back to the UTC. (7,0,2) 4. Taiwanese proposals Proposal form Taiwan to add 214 radical element: UTC supports additional study (consensus) Proposal to remove U+3004 since it is already coded at 4EDD (9:0:1) 5. Chu Nom project SVSCII is engaged in a project identifying the characters needed for Chu Nom and compare them with URO 2.0 and HCS-B for possible unification. 6. XJIS to Unicode mapping project Over several meetings the SC developed a proposal to define a default mapping for the Shift-JIS user defined character area to the Unicode Private Use Area. However, after last minute objections were raised which could not be accommodated, the project was withdrawn. It was distributed as paper UTC92-022 for information. 7. Indirect encoding of characters Proposal to develop an indirect encoding ("spelling") of rare Han characters to alleviate the impending space problem facing Unicode. Possible solutions include these mechanisms Spelling abstract determinant Bound X-eme abstract determinant Postfix plane shifter 8. Han variant mapping project A contextual/national B Font substitution C Rearrangement D Semantic Substitution E Numeric Variants E. Implementation SC -------------------- 1. Charter for Implementation SC Identify Unicode implementation issues Recommend solutions Examples: * Enable textual data portability * Internationalization issues such as: * Conversion public and industry standards to/from Unicode * Character attributes * Casing * String Parsing * Bidi to/from Visual * Normalization to/from precomposed * Compatibility mapping * Comparison language sensitive * Comparison (levels of weak equivalence) * Next/previous character / word boundaries / line breaking * UTF * Traditional to Simplified * Compression (optimized for Unicode) * Unicode detection heuristic Non-examples might include: * keyboard layouts, * date and time formats, * tagging mechanisms, * message catalogs Output of the SC will be recommendations to UTC for: * Additions to standard * Unicode Technical Papers * Liaison Statements * Reference Code, Data, Texts * API * Tool kit * Font kit SC Recommends that this Charter be ratified by UTC as instructions to the Implementation SC and communicated to outside interested groups. UTC approved this charter for Implementation SC (8,0,1) F. Workshop Subcommittee ------------------------ The Unicode implementers workshop in Merrimack attracted more than 130 people from about 30 companies. It was a success. The Unicode course rehearsal in Redmond attracted 70 people and provided valuable feedback for improving the Unicode course. The next workshops are planned for: UIW #3 August 6-7, Bay Area July 15, UIW SC meeting Cutoff for paper and slides: June 25 UIW #4 October 5-6, Sulzbach (Rhein-Main area), Germany, hosted by Unisys Fallback: November 16-17 UTC approved dates and locations for the above events (9:0:0) Tentative: UIW #5 In Japan, Spring 1993 UTC acknowledges the efforts of Tim Greenwood and Digital in hosting the UIW#2 in Merrimack and Microsoft in hosting the Unicode course rehearsal.
