Experiment with your <code class="module"><a href="../mod/mod_charset_lite.html">mod_charset_lite</a></code> configuration to ensure that it performs the desired function.</p> <p><code class="module"><a href="../mod/mod_charset_lite.html">mod_charset_lite</a></code> allows the administrator to specify the source character set of objects as well as the character set they should be translated into before sending to the client. <code class="module"><a href="../mod/mod_charset_lite.html">mod_charset_lite</a></code> does not translate the data itself but instead tells Apache what translation to perform. <code class="module"><a href="../mod/mod_charset_lite.html">mod_charset_lite</a></code> is applicable to EBCDIC and ASCII host environments. In an EBCDIC environment, Apache normally translates text content from the code page of the Apache process locale to ISO-8859-1. <code class="module"><a href="../mod/mod_charset_lite.html">mod_charset_lite</a></code> can be used to specify that a different translation is to be performed. In an ASCII environment, Apache normally performs no translation, so <code class="module"><a href="../mod/mod_charset_lite.html">mod_charset_lite</a></code> is needed in order for any translation to take place.</p> <p>This module provides a small subset of configuration mechanisms implemented by Russian Apache and its associated <code>mod_charset</code>.</p></div><div id="quickview"><h3 class="directives">Directives</h3><ul id="toc"><li><img alt="" src="../images/down.gif" /> <a href="#charsetdefault">CharsetDefault</a></li><li><img alt="" src="../images/down.gif" /> <a href="#charsetoptions">CharsetOptions</a></li><li><img alt="" src="../images/down.gif" /> <a href="#charsetsourceenc">CharsetSourceEnc</a></li></ul><h3>Topics</h3><ul id="topics"><li><img alt="" src="../images/down.gif" /> <a href="#problems">Common Problems</a></li></ul></div><div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div><div class="section"><h2><a name="problems" id="problems">Common Problems</a></h2> <h3>Invalid character set names</h3> <p>The character set name parameters of <code class="directive"><a href="#charsetsourceenc">CharsetSourceEnc</a></code> and <code class="directive"><a href="#charsetdefault">CharsetDefault</a></code> must be acceptable to the translation mechanism used by APR on the system where <code class="module"><a href="../mod/mod_charset_lite.html">mod_charset_lite</a></code> is deployed. These character set names are not standardized and are usually not the same as the corresponding values used in http headers.
