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

com.ibm.icu.text.UnicodeSet.indexOf()
Returns the index of the given character within this set, where the set is ordered by ascending code point. If the character is not in this set, return -1. The inverse of this method is charAt(). @return an index from 0..size()-1, or -1 @stable ICU 2.0
