System.out.println(str); String str1 = new String(str.getBytes("ISO-8859-1"), "utf-8"); System.out.println(str1); String str2 = new String(str.getBytes("gb2312"), "utf-8"); System.out.println(str2); String str3 = new String(str.getBytes("gbk"), "utf-8"); System.out.println(str3);
str.getBytes(charsetName);charsetName是原本字符的编码
"utf-8"是将str转换为utf-8编码。
