Examples of com.ibm.icu.text.UnicodeSet.complement()

com.ibm.icu.text.UnicodeSet.complement()
Complements the specified range in this set. Any character in the range will be removed if it is in this set, or will be added if it is not in this set. If end > start then an empty range is complemented, leaving the set unchanged. @param start first character, inclusive, of range to be removedfrom this set. @param end last character, inclusive, of range to be removedfrom this set. @stable ICU 2.0
