在java中将UTF-16 unicode字符转换为UTF-8

Question

当我得到JSON时，有\ u003c和\ u003e而不是＆lt;和＆gt;。我想在java中将它们转换回utf-8。任何帮助将受到高度赞赏。谢谢。

Answer 1

try {
    // Convert from Unicode to UTF-8
    String string = "\u003c";
    byte[] utf8 = string.getBytes("UTF-8");

    // Convert from UTF-8 to Unicode
    string = new String(utf8, "UTF-8");
} catch (UnsupportedEncodingException e) {
}

Answer 2

您可以尝试将字符串转换为字节数组

byte[] utfString = str.getBytes("UTF-8") ;

并通过指定像

这样的UTF-8编码将其转换回字符串对象

str = new String(utfString,"UTF-8") ;
