unicode -> 中文

public String unicodeToGbk(String unicodeText) { Pattern p = Pattern.compile("[u][//w]{4}"); Matcher m = p.matcher(unicodeText); StringBuilder sbu = new StringBuilder(); while (m.find()) { String str = m.group(); System.out.PRintln(str); sbu.append((char) (Integer.parseInt(str.substring(1), 16))); } return sbu.toString();}

中文 -> unicode

public static String GbkToUnicode(String gbk) { StringBuilder sbu = new StringBuilder(); for (char c : gbk.toCharArray()) { sbu.append("//u").append(Integer.toHexString(c)); } return sbu.toString();}

测试

public static void main(String[] args) { String text = "//u5f00//u59cb//u4efb//u52a1"; String u2g = Test.unicodeToGbk(text); System.out.println(u2g); System.out.println(Test.GbkToUnicode(u2g));}
