如何在Java中修改字符串中的Unicode \ u0085字符

Question

我無法修剪Java中的unicode控制字符\u0085。你怎麼能這樣做？

String str = "\u0000\u001f\u0085 hi \n" 
PrintStream out = new PrintStream(System.out, true, "UTF-8"); 
out.println(teststr); 
String st = teststr.replaceAll("\\p{Cntrl}", ""); 
out.println(st); 

字符\u0085被打印爲？似乎並沒有被取代。

import java.util.regex.Matcher; 
    import java.util.regex.Pattern; 

    public static String trimUtf16(String test) { 
     Pattern unicode = Pattern.compile("[^\\x00-\\x7F]", 
       Pattern.UNICODE_CASE | Pattern.CANON_EQ 
         | Pattern.CASE_INSENSITIVE); 
     Matcher matcher = unicode.matcher(test); 
     test = matcher.replaceAll(" "); 
     return test; 
    } 
    System.out.println(trimUtf16("\u0000\u001f\u0085 hi \n"));// hi
