Unicode® Technical Committee Historical Documents
This page contains information about Unicode Technical Committee (UTC)
historical documents, including the earliest document registers.
Quick links to all of the recent document registers, organized year-by-year,
are provided in the following table.
Complete UTC Document Registers, 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.
The UTC document registry has been continuously maintained
since the founding of the UTC in January, 1991. Document registers after 1996 are complete
electronic archives of documents submitted to the UTC.
The document registers for 1999 onward usually contain links to all of the documents
for a given year. Prior to
1999, some electronic documents are available but the digital archives are
The document registers for 1991-1996 are
available in HTML, PDF and MS Word format, although they contain no links to
digital documents. All committee documents during that period were
distributed in hard copy only.
Note: The HTML versions of these early registers
have known character display issues, as they are encoded in CP1252, but
the Unicode webserver currently serves pages as UTF-8. This deficiency may
be corrected in the future, but for the moment, the PDF versions of those
register pages are more reliable for viewing.
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 in 2012, INCITCS/L2 documents are 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 continuity and consistency
with the existing document tooling.
For details regarding the early history of the document
registry and UTC meetings, see also
Earlier UTC Meetings.
The 1997 Directory contains a partial document set. Most of these documents
are linked from the 1997 register.
The 1996 Directory contains agendas for UTC #69 and UTC #71.
The Historical Documents Directory contains a miscellany of early
documents, many 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. Most of the agenda and minutes documents in this
directory and the 1996 directory are accessible in a more systematic manner via the links located on
the Earlier UTC Meetings page.
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
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.
