java实现十六进制字符unicode与中英文转换示例
关于unicode和utf的关系，可以简单的记忆：unicode是一个编码组织、一个编码规范、在java中指utf-16；utf是unicode编码的translation转换格式，以便于很好地在网络中传递、在存储媒介汇总保存，于是utf存在多种格式，如8、16、32，而关联le、te的区别，unicode编码格式才会有以下过程中的10种。

}

public static void str4all(string ustr) throws unsupportedencodingexception{

byte[] bs = new byte[ustr.length()/2];
for (int i = 0; i < bs.length; i++) {
bs[i] = (byte) integer.parseint(ustr.substring(i*2, i*2+2), 16);
}
system.out.println(new string(bs, "utf-8"));
// 16
