<h2>Native2Ascii</h2>
<h3>Description:</h3>
<p>
Converts files from native encodings to ASCII with escaped Unicode.
A common usage is to convert source files maintained in a native
operating system encoding, to ASCII prior to compilation.
</p>
<p>
Files in the directory <em>src</em>
are converted from a native encoding to ASCII.
By default, all files in the directory are converted.
However, conversion may be limited to selected files using
<em>includes</em> and <em>excludes</em> attributes.
For more information on file matching patterns,
see the section on
<a href="../dirtasks.html#directorybasedtasks">directory based tasks</a>.
If no <em>encoding</em> is specified,
the default encoding for the JVM is used.
If <em>ext</em> is specified, then output files are renamed
to use it as a new extension.
More sophisticated file name translations can be achieved using a nested
<em><code><mapper></code></em> element. By default an
<a href="../CoreTypes/mapper.html#identity-mapper">identity mapper</a> will be used.
If <em>dest</em> and <em>src</em> point to the same directory,
the <em>ext</em> attribute or a nested <em><code><mapper></code></em>
is required.
</p>
<p>
This task forms an implicit <a href="../CoreTypes/fileset.html">File Set</a>,
and supports all attributes of <code><fileset></code>
(<code>dir</code> becomes <code>src</code>) as well as
nested <code><include></code>, <code><exclude></code>,
and <code><patternset></code> elements.

<h3>Examples</h3>
<pre>
<native2ascii encoding="EUCJIS" src="srcdir" dest="srcdir"
includes="**/*.eucjis" ext=".java"/>
</pre>
<p>
Converts all files in the directory <em>srcdir</em>
ending in <code>.eucjis</code> from the EUCJIS encoding to ASCII
and renames them to end in <code>.java</code>.
</p>
<pre>
<native2ascii encoding="EUCJIS" src="native/japanese" dest="src"
includes="**/*.java"/>
</pre>
<p>
Converts all the files ending in <code>.java</code>
in the directory <em>native/japanese</em> to ASCII,
placing the results in the directory <em>src</em>.
The names of the files remain the same.
