UnicodeĀ® Technical Committee Historical Documents

Latest Register

This page contains information about Unicode Technical Committee (UTC) historical documents, including the earliest document registers.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.

Document Search

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.

History of the Document Registry

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 incomplete.

The document registers for 1991-1996 are available in 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.

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.

Historical Directories

The Historical Documents Directory contains a miscellany of early documents, many from before 1996.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.

Archived Standards Registers

The Unicode website hosts some archived registers of older standards activities for historical reference. These registers were cleaned up in 2016 for better display, and have had nonfunctional links removed, but are no longer actively maintained.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.
