Note that the method <code>isLowerCase</code> <a href="javalang.doc15.html#30199">(§20.5.11)</a> will not necessarily return <code>true</code> when given the result of the <code>toLowerCase</code> method.<p>
<a name="23423"></a>
[This specification for the method <code>toLowerCase</code> is scheduled for introduction in Java version 1.1, either as defined here, or updated for Unicode 2.0; see <a href="javalang.doc4.html#14345">§20.5</a>. In previous versions of Java, this method returns its argument for all arguments larger than <code>\u00FF</code>.]<p>

If the character <code>ch</code> has an uppercase equivalent specified in the Unicode attribute
table, then that uppercase equivalent character is returned. Otherwise, the argument
<code>ch</code> is returned.

The uppercase equivalents specified in the Unicode attribute table for Unicode 1.1.5 as corrected above, are as follows, where character codes to the right of arrows are the uppercase equivalents of
