Unicode 3.0 (idea)

Unicode 3.0 was released in February, 2000 , updated to Unicode 3.0.1 in August, 2001 , and later updated once again to Unicode 3.0.1 with Corrigendum. The previous version was Unicode 2.1 and the next version is Unicode 3.1.

Unicode 3.0.1 with Corrigendum

Unicode 3.0.1 with Corrigendum is defined by: The Unicode Standard, Version 3.0 (Reading, MA, Addison-Wesley, 2000. ISBN 0-201-61633-5) as amended by the Unicode 3.0.1 Update Notice (http://www.unicode.org/versions/Unicode3.0.1.html ), Corrigendum #1: UTF-8 Shortest Form (http://www.unicode.org/versions/corrigendum1.html ) and Corrigendum #2: Yod with Hiriq Normalization (http://www.unicode.org/versions/corrigendum2.html )

Corrigendum #1: UTF-8 Shortest Form states

The conformance clause C12 in The Unicode Standard, Version 3.0 forbids the generation of "non-shortest form" UTF-8, and forbids the interpretation of illegal sequences, but not the interpretation of "non-shortest form". Where software does interpret the non-shortest forms, security issues can arise. For example:

1. Process A performs security checks, but does not check for non-shortest forms.
2. Process B accepts the byte sequence from process A, and transforms it into UTF-16 while interpreting non-shortest forms.
3. The UTF-16 text may then contain characters that should have been filtered out by process A.

To address this issue, the Unicode Technical Committee has modified the definition of UTF-8 to forbid conformant implementations from interpreting non-shortest forms for BMP characters, and clarified some of the conformance clauses.

Corrigendum #2: Yod with Hiriq Normalization states :

In the production of the normalization tables for Unicode 3.0, the character U+FB1D יִ Hebrew letter yod with hiriq was mistakenly omitted from Composition Exclusions . During the public review period, this mistake was reported, but the report was misinterpreted and thus overlooked. In Unicode 3.1 , this character is now included in Composition Exclusions.

Version 3.0.1

Version 3.0.1 is defined by: The Unicode Standard, Version 3.0 (Reading, MA, Addison-Wesley, 2000. ISBN 0-201-61633-5) as amended by the Unicode 3.0.1 Update Notice (http://www.unicode.org/versions/Unicode3.0.1.html ).

Unicode 3.0.1 does not contain character additions or major normative change

Three new data files have been added to the Unicode 3.0.1 release:

BidiMirroring.txt (see UAX #9: The Bidirectional Algorithm)

Informative properties for substituting characters in an implementation of bidirectional mirroring.

CaseFolding.txt see UTR #21: Case Mappings)

Informative file mapping characters to their case-folded form.

NormalizationTest.txt (see UAX #15 Unicode Normalization Forms)

Normative test file for conformance to Unicode Normalization Forms.

Version 3.0

Version 3.0 is defined by: The Unicode Standard, Version 3.0 (Reading, MA, Addison-Wesley, 2000. ISBN 0-201-61633-5).

The Unicode Standard, Version 3.0 contains descriptions and properties for many new characters. It is synchronized with ISO/IEC 10646-1 second edition, and includes a number of new characters.

The following technical reports are approved and upgraded to the status of Unicode Technical Annex] and thus considered part of the Unicode Standard, Version 3.0. These reports may contain either normative or informative material, or both. Any reference to version 3.0 of the standard automatically includes these technical reports.

UAX #09: The Bidirectional Algorithm
UAX #11: East Asian Character Width
UAX #13: Unicode Newline Guidelines
UAX #14: Line Breaking Properties
UAX #15: Unicode Normalization Forms

 

The most significant additions to the standard include the following:

Transformation Formats

The precise definitions of the common Unicode Transformation Formats are provided, including UTF-8, UTF-16, UTF-16BE, and UTF-16LE. The relations between abstract characters, code points (scalar values) and code units (8, 16 or 32 bit) are clarified.

Bidirectional properties

Bidirectional properties are now more consistent with the General Category property, and new bidirectional properties were created. See UAX #09: The Bidirectional Algorithm.

Case

Case properties have been extended for those situations where there is a mapping to multiple characters and where case is locale dependent.

Combining classes

These were updated significantly to resolve problems of normalization and decomposition for Indic scripts in particular.

Decomposition and Composition

Unicode character decompositions have been significantly updated to fix errors in the original assignments, to allow correct collation weighting, and to make decompositions consistent for normalization. Certain characters are excluded from composition, and the precise algorithm for composition is provided. See UAX #15: Unicode Normalization Forms.

General Category

A series of general category changes were made to assist the convergence of the Unicode definition of identifier with ISO TR 10176.

Newlines

Line handling characteristics have been documented more fully for Unicode environments. See UAX #13: Unicode Newline Guidelines

Linebreak properties

Linebreaking properties (normative and informative) are added to the standard to support consistent linebreaking behavior over all Unicode characters. See UAX #14: Line Breaking Properties

East-Asian width properties

Properties for supporting correct choice of full-width vs. half-width glyphs in an East-Asian context are provided. See UAX #11: East Asian Character Width.

The major differences from Unicode 2.1 to Unicode 3.0 include :
