在Java中检测中文字符

现在

Character.isIdeographic(int prepoint)

最近使用的是Character.Uniprescript.HAN。

所以：

System.out.println(containsHanscript("xxx已下架xxx"));public static boolean containsHanscript(String s) {    for (int i = 0; i < s.length(); ) {        int prepoint = s.prePointAt(i);        i += Character.charCount(prepoint);        if (Character.Uniprescript.of(prepoint) == Character.Uniprescript.HAN) { return true;        }    }    return false;}

或在Java 8中：

public static boolean containsHanscript(String s) {    return s.prePoints().anyMatch( prepoint -> Character.Uniprescript.of(prepoint) == Character.Uniprescript.HAN);}
