About Unicode® Technical Notes

Unicode Technical Notes provide information on a variety of topics related to the Unicode Standard and internationalization technologies.

These technical notes are independent publications, not approved by any of the Unicode Technical Committees, nor are they part of the Unicode Standard or any other Unicode specification. Publication does not imply endorsement by the Unicode Consortium in any way.

Updates

Readers should be aware of the fact that Unicode Technical Notes are not updated on a regular basis, if at all. It is the responsibility of the reader to determine whether a particular document has become out-of-date. Unicode Technical Notes are not maintained by the Unicode Technical Committee or the UTC Editorial Working Group, so there are no guarantees that they will be updated to track changes in the Unicode Standard or other Unicode Consortium standards.

From time to time, an author may be requested to update material in a Unicode Technical Note for consistency with later versions of the Unicode Standard or other standards, or to correct other errors in the Note. Responsibility for maintenance of the Unicode Technical Note lies solely with the author, and the author may or may not choose to update the Note. In some instances, such as Unicode Technical Notes consisting of particular presentations at a Internationalization and Unicode Conference or other conference, the Note may simply be considered an archival record, unsuitable for updating.

The Unicode Consortium reserves the right to withdraw a Unicode Technical Note from circulation at any time for any reason.

Versioning

Unicode Technical Notes may be versioned by the authors, so that a Note can be updated while keeping prior posted versions stable for reference. No content changes are made after a Note is posted without incrementing the version number. Unless a prior version is withdrawn, it will remain on the server to allow for stable references. If a Note is withdrawn, then the last version of the Note will describe its status and whether the content is known to be maintained elsewhere (such as in part of a Unicode Technical Report or on another site).

Submissions

All submissions of proposed Technical Notes are governed by the Unicode Intellectual Property, Licensing, and Technical Contribution Policies. Authors of proposed Technical Notes must sign the appropriate contributor license agreement (CLA) as provided in these policies. Proposed Technical Notes will not be accepted without the appropriate CLA in place.

Before acceptance for posting, the Notes are reviewed by a group designated by the UTC Editorial Working Group. The only criteria for submission are that in the judgment of the reviewers the subject matter is useful and the content does not contravene the Unicode Standard or other Unicode specifications.

The suggested submission format is HTML using the Unicode Technical Note Template. Alternatively, an author may supply a document in PDF format or in another HTML style. In that case, however, for consistency and maintenance purposes, the author must also provide a cover page using the Basic Unicode Technical Note Cover Template.  All HTML submissions must pass the W3C HTML Validator.

If the submission is in PDF, authors should include the following text at the end of the document, filling in the [authors] placeholder with appropriate names and adjusting the copyright year as appropriate.
