java.text.Normalizer

Java 6부터 추가된 Normalizer는 한글 자동완성을 처리하기에 적합한 방법이 아닙니다.

 import java.text.Normalizer
 
 val str = "한글"
 val q1 = "ㅎ"
 val q2 = "하"
 
 val nfdStr = Normalizer.normalize(str, Normalizer.Form.NFD)
 
 
 val nfdQ1 = Normalizer.normalize(q1, Normalizer.Form.NFD)
 val nfdQ2 = Normalizer.normalize(q2, Normalizer.Form.NFD)
 
 nfdStr.startsWith(nfdQ1)
 // false
 
 nfdStr.startsWith(nfdQ2)
 // true
 
 val nfkdStr = Normalizer.normalize(str, Normalizer.Form.NFKD)
 
 val nfkdQ1 = Normalizer.normalize(q1, Normalizer.Form.NFKD)
 val nfkdQ2 = Normalizer.normalize(q2, Normalizer.Form.NFKD)
 
 nfkdStr.startsWith(nfkdQ1)
 // true
 
 nfkdQ2.startsWith(nfkdQ2)
 // true

 nfkdStr.startsWith(nfkdQ1)
 // false
