+
+<h2>Introduction</h2>
+
+<p>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 <i><a href="http://www.unicode.org/unicode/uni2book/u2.html">The
+
+Unicode Standard</a></i>.</p>
+
+<p>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.</p>
+
+<p>For more information on versions of the Unicode Standard and how to reference
+
+them, see <a href="http://www.unicode.org/unicode/standard/versions/">http://www.unicode.org/unicode/standard/versions/</a>.</p>
+
+<h2>Conformance</h2>
+
+<p>Character properties may be either normative or informative. <i>Normative</i>
+
+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 <i>normative</i> when applied to a property or field of
+
+the Unicode Character Database, does <i>not</i> 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<i> informative </i>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.</p>
+
+<h2>Files</h2>
+
+<p>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.</p>
+
+<p><b>UnicodeData.txt (Chapter 4)</b>
+
+<ul>
+
+ <li>The main file in the Unicode Character Database.</li>
+
+ <li>For detailed information on the format, see <a href="UnicodeData.html">UnicodeData.html</a>.
+
+ This file also characterizes which properties are normative and which are
+
+ informative.</li>

+ and <i>Mathematical</i>, among others.</li>
+
+</ul>
+
+<p><b>SpecialCasing.txt (Chapter 4)</b>
+
+<ul>
+
+ <li>List of informative special casing properties, including one-to-many
+
+ mappings such as SHARP S => "SS", and locale-specific mappings,
+
+ such as for Turkish <i>dotless i</i>.</li>
+
+</ul>
+
+<p><b>Blocks.txt (Chapter 14)</b>
+
+<ul>

+
+ algorithmically.</li>
+
+</ul>
+
+<p><b>ArabicShaping.txt (Section 8.2)</b>
+
+<ul>
+
+ <li>Basic Arabic and Syriac character shaping properties, such as initial,
+

+
+ of Arabic and Syriac. </li>
+
+</ul>
+
+<p><b>NamesList.txt (Chapter 14)</b>
+
+<ul>
+
+ <li>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. </li>
+
+ <li><b>Note: </b>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.</li>
+
+</ul>
+
+<p><b>Index.txt (Chapter 14)</b>
+
+<ul>
+
+ <li>Informative index to Unicode characters, as printed in the Unicode
+
+ Standard</li>
+
+ <li><b>Note: </b>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.</li>

+
+ properties are informative and which are normative, consult UTR#14.</li>
+
+</ul>
