Unicode® 1.0
Version 1.0 has been superseded by the
latest version
of the Unicode Standard.
 |
|  |
Version 1.0 of the Unicode Standard consists of
the core specification, The Unicode Standard,
Version 1.0, Volumes 1 and 2, and the code charts for this version. See also the
Version 1.0.1 Notice Page.
The core specification gives the general principles,
requirements for conformance, and guidelines for implementers. The
code charts show representative glyphs for all the Unicode
characters. This early version contained no machine-readable files for
the Unicode Character Database; instead, the printed standard contained
information about character properties and mappings.

A complete specification of the contributory files for Unicode 1.0
is found on the page
Components for 1.0.1.
Online Edition
This online edition of The Unicode Standard, Version 1.0,
Volume 1 (ISBN 0-201-56788-1) and Volume 2 (ISBN 0-201-60845-6),
provides a digital archive of this early version of the Unicode Standard,
for historical purposes. To view the text, follow the navigation
links on this page. Although this version is out of print,
normative references to the Unicode Standard, Version 1.0 should continue
to use the printed edition.
For this digital archive, both Volume 1 and Volume 2 are presented together.
A full set of
code charts was not available until the publication of Volume 2, so it does not
make much sense to document Volume 1 alone.
Because the pdf files are scanned from hard copy, they
are much larger than the pdf files for later versions, which were produced
directly from the editing tools. Sizes of the individual chapters and
other files are not individually noted, but most of them are large.
Overview
Unicode 1.0 is a major version
of the Unicode Standard. It was the first published version of the standard.
The core specification, The Unicode Standard, Version 1.0
contains descriptions
and properties for many characters. It was published prior to the publication of
ISO/IEC 10646-1:1993. Volume 1 corresponds to Unicode Version 1.0.0, published in October, 1991. Volume 2 was published 8 months later.
In addition to printing all of the unified CJK ideographs, Volume 2
made a number of small changes and corrections to Volume 1. At the time Volume 2 was
published in mid 1992, the merger with ISO/IEC 10646 was already underway, but not
all of the details of that merger had been fully decided. A few of the changes to the Unicode Standard specified in
Volume 2 anticipated the merger, but more complete details were distributed
in a separate short specification known as the
Version 1.0.1 Notice Page.
Unicode 1.0 also contained some early implementation guidelines. Extensive mapping
tables were printed in both volumes, including the earliest source references
defining the Han unification. No online mapping tables or other property-related
tables were posted online at the time, but starting in 1992 a diskette containing
the mapping tables was made available on request from the Unicode Consortium office.
Unicode Character Database
Although no online data files were posted in 1992, and the format of
UnicodeData.txt was not even invented until 1995, some information about
character properties is now available for this Online Edition of Unicode 1.0.
In 2004 an effort was made to reconstruct the likely intent of the Unicode
Technical Committee regarding character properties for Unicode 1.0, using
the UnicodeData.txt format, to facilitate comparison with later versions
of the standard.
- Reconstructed Version 1.0.0 UnicodeData.txt
- Reconstructed Version 1.0.1 UnicodeData.txt
Those two reconstructed data files contain extensive caveats regarding their use.
Note that the data they contain did not yet exist when Unicode 1.0 implementations
were under development. The property values were reconstructed long after the fact,
and are only posted for historical interest and research. The Version 1.0.0 data file
is limited to the repertoire documented in Volume 1 of Unicode 1.0. The Version 1.0.1
data file includes the unified CJK ideographic repertoire from Volume 2 of Unicode
1.0, as well as the limited changes for Version 1.0.1 that were published in
Section 1.3, Specific Changes to Align Code Positions and Repertoire in Volume 2.
The Version 1.0.1 data file does not include the more extensive and detailed changes
for Version 1.0.1 that were specified in the
Version 1.0.1 Notice Page
and which anticipated the Unicode 1.1 Unicode Character Database.
