Core.LegacyEntityDecoder
TYPE: bool
VERSION: 4.9.0
DEFAULT: false
--DESCRIPTION--
<p>
Prior to HTML Purifier 4.9.0, entities were decoded by performing
a global search replace for all entities whose decoded versions
did not have special meanings under HTML, and replaced them with
their decoded versions. We would match all entities, even if they did
not have a trailing semicolon, but only if there weren't any trailing
alphanumeric characters.
</p>
<table>
<tr><th>Original</th><th>Text</th><th>Attribute</th></tr>
<tr><td>&yen;</td><td>¥</td><td>¥</td></tr>
<tr><td>&yen</td><td>¥</td><td>¥</td></tr>
<tr><td>&yena</td><td>&yena</td><td>&yena</td></tr>
<tr><td>&yen=</td><td>¥=</td><td>¥=</td></tr>
</table>
<p>
In HTML Purifier 4.9.0, we changed the behavior of entity parsing
to match entities that had missing trailing semicolons in less
cases, to more closely match HTML5 parsing behavior:
</p>
<table>
<tr><th>Original</th><th>Text</th><th>Attribute</th></tr>
<tr><td>&yen;</td><td>¥</td><td>¥</td></tr>
<tr><td>&yen</td><td>¥</td><td>¥</td></tr>
<tr><td>&yena</td><td>¥a</td><td>&yena</td></tr>
<tr><td>&yen=</td><td>¥=</td><td>&yen=</td></tr>
</table>
<p>
This flag reverts back to pre-HTML Purifier 4.9.0 behavior.
