+<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>
