<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>
