<section><title>Codepage support</title>
<fixme author="Rainer Klute">Improve codepage support!</fixme>
<p>The property with ID 1 holds the number of the codepage which was used
to encode the strings in this section. The present HPSF codepage support
is still very limited: When reading property value strings, HPSF
distinguishes between 16-bit characters and 8-bit characters. 16-bit
characters should be Unicode characters and thus be okay. 8-bit
characters are interpreted according to the platform's default character
set. This is fine as long as the document being read has been written on
a platform with the same default character set. However, if you receive a
document from another region of the world and want to process it with
HPSF you are in trouble - unless the creator used Unicode, of course.</p>
to encode the strings in this section. If this property is not available
in a section, the platform's default character encoding will be
used. This works fine as long as the document being read has been written
on a platform with the same default character encoding. However, if you
receive a document from another region of the world and the codepage is
undefined, you are in trouble.</p>
<p>HPSF's codepage support is as good as the character encoding support of
the Java Virtual Machine (JVM) the application runs on. If HPSF
encounters a codepage number it assumes that the JVM has a character
encoding with a corresponding name. For example, if the codepage is 1252,
HPSF uses the character encoding "cp1252" to read or write strings. If
the JVM does not have that character encoding installed or if the
codepage number is illegal, an UnsupportedEncodingException will be
thrown.</p>
<p>There are two exceptions to the rule that a character encoding's name
is derived from the codepage number by prepending the string "cp" to
it:</p>
<dl>
<dt>Codepage 1200</dt>
<dd>is mapped to the character encoding "UTF-16".</dd>
<dt>Codepage 65001</dt>
<dd>is mapped to the character encoding "UTF-8".</dd>
</dl>

<title>The Dictionary</title>
<p>What a dictionary is good for is explained in the <link
href="how-to.html">HPSF HOW-TO</link>. This chapter explains how it is
organized internally.</p>
<p>The dictionary has a simple header consisting of a single UInt value. It
tells how many entries the dictionary comprises:</p>
<table>
<tr>
<th>Name</th>
<th>Data type</th>
<th>Description</th>
</tr>
<tr>
<td>nrEntries</td>
<th>UInt</th>
<td>Number of dictionary entries</td>
</tr>
</table>
<p>The dictionary entries follow the header. Each one looks like this:</p>
<table>
<tr>
<th>Name</th>
<td>Data type</td>
<th>Description</th>
</tr>
<tr>
<td>key</td>
<td>UInt</td>
<td>The unique number of this property, i.e. the PID</td>
</tr>
<tr>
<td>length</td>
<td>UInt</td>
<td>The length of the property name associated with the key</td>
</tr>
<tr>
<td>value</td>
<td>String</td>
<td>The property's name, terminated with a 0x00 character</td>
</tr>
</table>
<p>The entries are not aligned, i.e. each one follows its predecessor
without any gap or fill characters.</p>

Add codepage support: Presently the bytes making out the string in a

Add resource bundles to

localized strings. Example: The property ID 4 could be mapped to "Author"
in English or "Verfasser" in German.
