It is anticipated that these problems will be corrected for Unicode version 2.0.
<p><a name="32372"></a>
Java 1.1 will include the methods defined here, either based on Unicode 1.1.5 or, we hope, updated versions of the methods that use the newer Unicode 2.0. The character attribute table for Unicode 2.0 is currently available on the World Wide Web as the file:<p>
<pre><a name="30276"></a>ftp://unicode.org/pub/MappingTables/UnicodeData-2.0.12.txt
</pre><a name="33816"></a>
If you are implementing a Java compiler or system, please refer to the page:
<p><pre><a name="33819"></a>http://java.sun.com/Series
</pre><a name="33820"></a>
which will be updated with information about the Unicode-dependent methods.
<p><a name="36558"></a>
The biggest change in Unicode 2.0 is a complete rearrangement of the Korean Hangul characters. There are numerous smaller improvements as well.<p>
<a name="33888"></a>
It is our intention that Java will track Unicode as it evolves over time. Given that full Unicode support is just emerging in the marketplace, and that changes in Unicode are in areas which are not yet widely used, this should cause minimal problems and further Java's goal of worldwide language support.<p>
