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

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.

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
