Introduction

+ +

The Unicode Character Database is a set of files that define the Unicode + +character properties and internal mappings. For more information about character + +properties and mappings, see The + +Unicode Standard.

+ +

The Unicode Character Database has been updated to reflect Version 3.0 of the + +Unicode Standard, with many characters added to those published in Version 2.0. + +A number of corrections have also been made to case mappings or other errors in + +the database noted since the publication of Version 2.0. Normative bidirectional + +properties have also been modified to reflect decisions of the Unicode Technical + +Committee.

+ +

For more information on versions of the Unicode Standard and how to reference + +them, see http://www.unicode.org/unicode/standard/versions/.

+ +

Conformance

+ +

Character properties may be either normative or informative. Normative + +means that implementations that claim conformance to the Unicode Standard (at a + +particular version) and which make use of a particular property or field must + +follow the specifications of the standard for that property or field in order to + +be conformant. The term normative when applied to a property or field of + +the Unicode Character Database, does not mean that the value of that + +field will never change. Corrections and extensions to the standard in the + +future may require minor changes to normative values, even though the Unicode + +Technical Committee strives to minimize such changes. An informative property + +or field is strongly recommended, but a conformant implementation is free to use + +or change such values as it may require while still being conformant to the + +standard. Particular implementations may choose to override the properties and + +mappings that are not normative. In that case, it is up to the implementer to + +establish a protocol to convey that information.

+ +

Files

+ +

The following summarizes the files in the Unicode Character Database. For + +more information about these files, see the referenced technical report or + +section of Unicode Standard, Version 3.0.

+ +

UnicodeData.txt (Chapter 4) + +

The main file in the Unicode Character Database.
For detailed information on the format, see UnicodeData.html. + + This file also characterizes which properties are normative and which are + + informative.

+ +

PropList.txt (Chapter 4) + +

Additional informative properties list: Alphabetic, Ideographic, + + and Mathematical, among others.

+ +

SpecialCasing.txt (Chapter 4) + +

List of informative special casing properties, including one-to-many + + mappings such as SHARP S => "SS", and locale-specific mappings, + + such as for Turkish dotless i.

+ +

Blocks.txt (Chapter 14) + +

List of normative block names.

+ +

Jamo.txt (Chapter 4) + +

List of normative Jamo short names, used in deriving HANGUL SYLLABLE names + + algorithmically.

+ +

ArabicShaping.txt (Section 8.2) + +

Basic Arabic and Syriac character shaping properties, such as initial, + + medial and final shapes. These properties are normative for minimal shaping + + of Arabic and Syriac.

+ +

NamesList.txt (Chapter 14) + +

This file duplicates some of the material in the UnicodeData file, and + + adds informative annotations uses in the character charts, as printed in the + + Unicode Standard.
Note: The information in NamesList.txt and Index.txt files matches + + the appropriate version of the book. Changes in the Unicode Character + + Database since then may not be reflected in these files, since they are + + primarily of archival interest.

+ +

Index.txt (Chapter 14) + +

Informative index to Unicode characters, as printed in the Unicode + + Standard
Note: The information in NamesList.txt and Index.txt files matches + + the appropriate version of the book. Changes in the Unicode Character + + Database since then may not be reflected in these files, since they are + + primarily of archival interest.

+ +
