- <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(s) or
