About Unicode® Technical Notes
Unicode Technical Notes provide information on a
variety of topics related to Unicode and internationalization
These technical notes are independent
publications, not approved by
any of the
Unicode Technical Committees, nor are they part of the
Standard or any other
Unicode specification. Publication
does not imply endorsement by the Unicode Consortium in any way.
These documents are not subject to the
Unicode Patent Policy.
Readers should be aware of the fact that 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a particular document has become out-of-date. Technical Notes are
not reviewed or maintained by the UTC or the Unicode Consortium
editorial committee, 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 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 Technical Note lies solely with the author,
and the author may or may not choose to update the
Note. In some instances, such as 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 Technical
Note from circulation at any time for any reason.
Technical Notes may be versioned by the authors, so
that a Technical 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version is withdrawn, it will remain on the server to allow for stable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 If a Note is withdrawn, then the last version of the Note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).
Before acceptance for posting, the Notes are reviewed
by a group designated by the
Editorial Committee. 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
The suggested submission format is HTML using the
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 Technical Note Cover Template.
All 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
their name(s) in the [authors] position and adjusting the copyright
year as appropriate.
