126<h2>Introduction</h2>
127
128<p>The Unicode Character Database is a set of files that define the Unicode
129
130character properties and internal mappings. For more information about character
131
132properties and mappings, see <i><a href="http://www.unicode.org/unicode/uni2book/u2.html">The
133
134Unicode Standard</a></i>.</p>
135
136<p>The Unicode Character Database has been updated to reflect Version 3.0 of the
137
138Unicode Standard, with many characters added to those published in Version 2.0.
139
140A number of corrections have also been made to case mappings or other errors in
141
142the database noted since the publication of Version 2.0. Normative bidirectional
143
144properties have also been modified to reflect decisions of the Unicode Technical
145
146Committee.</p>
147
148<p>For more information on versions of the Unicode Standard and how to reference
149
150them, see <a href="http://www.unicode.org/unicode/standard/versions/">http://www.unicode.org/unicode/standard/versions/</a>.</p>
151
152<h2>Conformance</h2>
153
154<p>Character properties may be either normative or informative. <i>Normative</i>
155
156means that implementations that claim conformance to the Unicode Standard (at a
157
158particular version) and which make use of a particular property or field must
159
160follow the specifications of the standard for that property or field in order to
161
162be conformant. The term <i>normative</i> when applied to a property or field of
163
164the Unicode Character Database, does <i>not</i> mean that the value of that
165
166field will never change. Corrections and extensions to the standard in the
167
168future may require minor changes to normative values, even though the Unicode
169
170Technical Committee strives to minimize such changes. An<i> informative </i>property
171
172or field is strongly recommended, but a conformant implementation is free to use
173
174or change such values as it may require while still being conformant to the
175
176standard. Particular implementations may choose to override the properties and
177
178mappings that are not normative. In that case, it is up to the implementer to
179
180establish a protocol to convey that information.</p>
