-/*******************************************************************************
-
-        A mutable set of Unicode characters and multicharacter strings.
-
-        Objects of this class represent character classes used in regular 
-        expressions. A character specifies a subset of Unicode code points. 
-        Legal code points are U+0000 to U+10FFFF, inclusive.
-
-        UnicodeSet supports two APIs. The first is the operand API that 
-        allows the caller to modify the value of a UnicodeSet object. It 
-        conforms to Java 2's java.util.Set interface, although UnicodeSet
-        does not actually implement that interface. All methods of Set are 
-        supported, with the modification that they take a character range 
-        or single character instead of an Object, and they take a UnicodeSet
-        instead of a Collection. The operand API may be thought of in terms
-        of boolean logic: a boolean OR is implemented by add, a boolean AND 
-        is implemented by retain, a boolean XOR is implemented by complement
-        taking an argument, and a boolean NOT is implemented by complement 
-        with no argument. In terms of traditional set theory function names, 
-        add is a union, retain is an intersection, remove is an asymmetric
-        difference, and complement with no argument is a set complement with
-        respect to the superset range MIN_VALUE-MAX_VALUE
-
-        The second API is the applyPattern()/toPattern() API from the 
-        java.text.Format-derived classes. Unlike the methods that add 
-        characters, add categories, and control the logic of the set, 
-        the method applyPattern() sets all attributes of a UnicodeSet 
-        at once, based on a string pattern.
-
-        See <A HREF="http://oss.software.ibm.com/icu/apiref/uset_8h.html">

+/*******************************************************************************
+
+        A mutable set of Unicode characters and multicharacter strings.
+
+        Objects of this class represent character classes used in regular 
+        expressions. A character specifies a subset of Unicode code points. 
+        Legal code points are U+0000 to U+10FFFF, inclusive.
+
+        UnicodeSet supports two APIs. The first is the operand API that 
+        allows the caller to modify the value of a UnicodeSet object. It 
+        conforms to Java 2's java.util.Set interface, although UnicodeSet
+        does not actually implement that interface. All methods of Set are 
+        supported, with the modification that they take a character range 
+        or single character instead of an Object, and they take a UnicodeSet
+        instead of a Collection. The operand API may be thought of in terms
+        of boolean logic: a boolean OR is implemented by add, a boolean AND 
+        is implemented by retain, a boolean XOR is implemented by complement
+        taking an argument, and a boolean NOT is implemented by complement 
+        with no argument. In terms of traditional set theory function names, 
+        add is a union, retain is an intersection, remove is an asymmetric
+        difference, and complement with no argument is a set complement with
+        respect to the superset range MIN_VALUE-MAX_VALUE
+
+        The second API is the applyPattern()/toPattern() API from the 
+        java.text.Format-derived classes. Unlike the methods that add 
+        characters, add categories, and control the logic of the set, 
+        the method applyPattern() sets all attributes of a UnicodeSet 
+        at once, based on a string pattern.
+
+        See <A HREF="http://oss.software.ibm.com/icu/apiref/uset_8h.html">
