From time to time the Unicode Consortium seeks wide public review and feedback for certain proposed actions. The purpose of the review is to elicit better information on the practical impact of such proposals on users or implementers as well as broaden the review of technical details. Any feedback on Public Review Issues will be used in the deliberations of the relevant Unicode Consortium technical committee. These open issues are listed here. Each issue has a number, title, summary, and deadline for receipt of public review comments. The link on the title points to a background document if any. When issues are closed, they are moved to the Resolved Issues pages (1-99, 100-199).
Public Review Issues are often targeted at the next version of a particular specification, such as the Unicode Standard. Where the specification is issued by the UTC, the closing date is set to one week before the next quarterly UTC meeting so that any feedback can be reviewed in the meeting. When the specification is due for release only after further meetings, the closing date is typically extended to each subsequent meeting to allow for more feedback.
Organizations and interested individuals are invited to submit public review comments on these issues. Feedback may be submitted via the online contact form; be sure to indicate the number and title of the issue you are providing feedback for, and try to be as explicit as possible in your suggestions. You may also wish to join the Unicode discussion list, where open discussion of all issues related to the Unicode Standard is held.
Material intended for consideration at a Unicode Technical Committee meeting must be submitted at least one week before the start of that meeting. Material intended for consideration by the CLDR Technical Committee should not use the reporting form; instead please see Filing CLDR Bug Reports.
Public Review issues are different from public resolutions of the Unicode Consortium on external issues of particular public importance to the computing industry. Such resolutions are documented as Unicode Consortium Public Positions.
Note: for constraints on proposed changes, see the Unicode Stability Policies.
| 148 | Unicode 5.2.0 Beta | 2009.08.03 |
|
The next version of the Unicode Standard will be Version 5.2.0. The beta information page for Unicode 5.2.0 is located at: http://www.unicode.org/versions/beta.html This version is planned for release in October 2009. A beta version of the 5.2.0 Unicode Character Database files is also available for public comment. We strongly encourage implementers to download these files and test them with their programs, well before the end of the beta period, August 3, 2009. These files are located in:
http://www.unicode.org/Public/5.2.0/ For detailed information and guidance on how to focus your review, see the section Notable Issues for Beta Testers on the beta page. The beta information page tells how to report comments and initiate discussions. |

| 147 | Proposed Deprecation of U+0673 ARABIC LETTER ALEF WITH WAVY HAMZA BELOW | 2009.08.03 |
|
The UTC has recently approved a proposal to encode an ARABIC WAVY HAMZA BELOW for a future version of the Unicode Standard. That character is used productively in Kashmiri and other languages, and is applied to letters other than ALEF. The intent is to deprecate the existing character U+0673 ARABIC LETTER ALEF WITH WAVY HAMZA BELOW, in favor of the sequence of an ALEF plus the new ARABIC WAVY HAMZA BELOW. (Because of normalization stability constraints, a canonical equivalence relation cannot be established.) The UTC is seeking feedback on whether U+0673 should be deprecated when ARABIC WAVY HAMZA BELOW is encoded. Pertinent information would include data on how widespread usage of this character is. Note that deprecation of a character does not mean removal of that character from the standard; it merely constitutes a strong recommendation not to use the character. |

| 146 | Suggested Restructuring of Text in Chapter 3 for Clarification of Unicode Normalization | 2009.08.03 |
| In order to consolidate the formal specification of Unicode normalization into a single location, text derived from UAX #15 will be incorporated into a rewritten Section 3.11 of the book text. The details are provided in the background document. This text change does not result in any substantive change to the definition of Unicode normalization. All Unicode strings currently in a normalization form will continue to be in that normalization form. All conformant implementations of the Unicode Normalization Algorithm will continue to be conformant. Feedback for this PRI should carefully consider the closely related PRI #145 which addresses the correlated changes of text required for UAX #15. | ||
| 145 | Proposed Update UAX #15: Unicode Normalization Forms | 2009.08.03 |
| This UAX will be updated for Unicode 5.2, and the proposed update is now open for general public review and comment. The main change for this update of the UAX is the proposed consolidation of the text for the formal specification of normalization forms into Chapter 3 of the book text. This means that the entire specification will be located in one place, instead of being split between two locations. This text change does not result in any substantive change to the definition of Unicode normalization. All Unicode strings currently in a normalization form will continue to be in that normalization form. All conformant implementations of the Unicode Normalization Algorithm will continue to be conformant. Feedback for this PRI should carefully consider the closely related PRI #146 which addresses the correlated changes of text for Chapter 3. The draft will be periodically updated during the development cycle for the release. Draft updated 2009-06-19. | ||
| 144 | Proposed Update UAX #42: Unicode Character Database in XML | 2009.08.03 |
| This UAX will be updated for Unicode 5.2, and the proposed update is now open for general public review and comment. The draft will be periodically updated during the development cycle for the release. Draft posted 2009-03-13: Added "two-code-points" as a datatype for code points in the schema and adjusted several definitions accordingly. | ||
| 143 | Proposed Update UTS #10: Unicode Collation Algorithm | 2009.08.03 |
| This UTS will be updated in parallel with Unicode 5.2, and the proposed update is now open for general public review and comment. The draft will be periodically updated during the development cycle for the release. Draft updated 2009-04-01. | ||
| 142 | Proposed Update UAX #41: Common References for Unicode Standard Annexes | 2009.08.03 |

| 138 | Proposed Update UAX #29: Unicode Text Segmentation | 2009.08.03 |
| This UAX will be updated for Unicode 5.2, and the proposed update is now open for general public review and comment. The draft will be periodically updated during the development cycle for the release. This update changes ZWSP to have the XX (Any) property for word boundary determination, fixing a problem which was causing words not to break at ZWSP. It also revises the section relating text boundaries to regular expressions. Draft updated 2009-03-31. | ||
| 137 | Proposed Update UAX #24: Unicode Script Property | 2009.08.03 |
| This UAX will be updated for Unicode 5.2, and the proposed update is now open for general public review and comment. The draft will be periodically updated during the development cycle for the release. Draft updated 2009-03-02: Section 3 has been substantially rewritten, in particular to distinguish clearly between script designators and script property value aliases. | ||

There are explicit notes requesting feedback on three open issues whose resolution could have an effect on how bidi text is displayed. Feedback is welcome on these issues. For a listing of the changes with links to the affected text, see http://www.unicode.org/reports/tr9/tr9-20.html#Modifications. Draft updated 2009-06-16. | ||
| 133 | Proposed Draft UTS #46: Unicode IDNA Compatible Preprocessing | 2009.08.03 |
| This Proposed Draft UTS provides a specification for an internationalized domain name preprocessing step that is intended for use with IDNAbis, the projected update for Internationalized Domain Names. The proposed specification maintains compatibility with IDNA2003 (the current version of Internationalized Domain Names), and consistently extends that mechanism for characters introduced in any later Unicode version. | ||
| 128 | Proposed Update UTS #37: Ideographic Variation Database | 2009.08.03 |
| The purpose of this second draft of the Proposed Update is to clarify the conditions under which a glyphic subset is appropriate for a given base character, following the UTC discussion. Details are in the background document. Draft updated 2009-05-21. | ||
| 127 | Proposed Update UAX #44: Unicode Character Database | 2009.08.03 |
