<p>Normalization filtered by a <a class="el" href="classUnicodeSet.html" title="A mutable set of Unicode characters and multicharacter strings.">UnicodeSet</a>. </p>
<p>Normalizes portions of the text contained in the filter set and leaves portions not contained in the filter set unchanged. Filtering is done via <a class="el" href="classUnicodeSet.html#ae429f2e852471745b94d6dba3dc38440" title="Returns the length of the initial substring of the input string which consists only...">UnicodeSet::span</a>(..., USET_SPAN_SIMPLE).

This class implements all of (and only) the <a class="el" href="classNormalizer2.html" title="Unicode normalization functionality for standard Unicode normalization or for using...">Normalizer2</a> API. An instance of this class is unmodifiable/immutable but is constructed and must be destructed by the owner. </p>
