Unicode® Technical Committee Document Registry
Latest Register
This is the home of the Unicode Technical Committee (UTC) document registry.
Links to all of the document registers, organized year-by-year,
are provided in the following table.
Complete List of UTC Document Registers, By Year
For completeness, the list includes X3L2 (later L2) document registers from prior to the
time when the UTC and L2 document registers were jointly maintained.
The Topical Documents page contains an index of links to certain
sets of documents organized by topic, rather than by year.
UTC Document Search
provides a way to find documents by number.
This search can also be used to find a particular revision of
a document that has multiple revisions posted in the document register.
This search works for documents with "L2" designations starting from
1997, but not for earlier years, nor for documents with "UTC" designations.
For instructions on document submission, see
How to Submit Proposal Documents and
Submitting Character Proposals.
The Proposal Summary Form is required for some types of submissions.
The UTC maintains the Roadmaps to Unicode together with WG2.
The Roadmaps contain current allocations of standardized characters
and proposed allocations for future characters, to help guide both
the authors of character proposals and the review of those proposals by the UTC and WG2.
The Pipeline page summarizes, in detail, all currently
approved characters and scripts that are in various stages of ISO
review and/or balloting, and which have not yet been published
in any version of the Unicode Standard. This page is also actively used
to guide proposal review.
The UTC document registry has been continuously maintained
since the founding of the UTC in January, 1991. The separate X3L2 document
register goes back as far as 1985. The document registers listed here are
as complete as possible, given current information. They are occasionally
updated as further historical research reveals the need for corrections or
illuminates former gaps in the record. Note that particularly for early
periods, the document registers may depart significantly from their original
form. The format of document registers has changed over the years, but has been
regularized here, for ease of reference.
Prior to 1997, all committee documents were distributed in hard copy only.
During 1997 and 1998, some documents were also posted contemporaneously in
electronic copies. From 1999 onward nearly all documents were made
available electronically, and the document links are live and stable in these
document registers.
Links to documents prior to 1999 are occasionally activated as scanned copies
of surviving paper documents become available, or as surviving electronic
copies of drafts of documents turn up.
In 2000 the registers for INCITS/L2 and for the UTC were
combined into jointly maintained registers, with a uniform numbering scheme, and are complete
through 2011. Starting from 2012, INCITCS/L2 documents have been maintained separately in the
ICMS system at http://www.incits.org/ and use a separate numbering system.
The UTC registers for starting from 2012 still use "L2" prefixes, for historical continuity and for consistency
with the existing document search tooling.
For further details regarding the early history of the document
registry and UTC meetings, see also
Earlier UTC Meetings.
The Historical Documents Directory contains a miscellany of early
documents, most from before 1996. Many of these documents are in rough form. Some may not
display well in modern browsers or may have character set issues.
The Unicode website hosts some archived registers of older standards activities
for historical reference. These registers were cleaned up in 2016 for better display,
and have had nonfunctional links removed, but are no longer actively maintained.
The List of Character Set Registrations shows activity from the
period 1998 to 2000, when INCITS/L2 was involved in character set registrations
according to ISO 2375, and applications for character set registrations were
hosted in the UTC document registry. The actual International Register of Coded Character Sets
to be Used with Escape Sequences can currently be found
here.
The SC2 Standards page lists all SC2 document numbers associated with
the ISO/IEC 10646, 14651, and 8859 series standards that INCITS/L2 was concerned
with. These documents include various ballot documents and votes taken on them.
The list was maintained during the period 2004 through 2011. All of the old live links to
documents on that page have been disabled, because of the restructuring of access
to documents on the current SC2 website and because of ISO constraints on public
access to committee documents related to current or historic balloting.
