android - 在 Java 中将字符串 ISO8859-1 转换为 UTF-8

Question

我有一个 Q-encoded字符串变量:

String s = "=?ISO-8859-1?Q?Merve_G=FCl?=";

我想用真实字符在屏幕上写下它:“Merve Gül”。

我该怎么做？

@尼克

String string = "=?ISO-8859-1?Q?Merve_G=FCl?=";
QCodec q = new QCodec();
        try 
        {
            q.decode(string);
            System.out.println(q.decode(kimdenIsim));
        } catch (DecoderException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } 

我收到这个错误:

第 4 行错误显示:q.decode(string);

Answer 1

根据 this答案是否可能这样。为此，您需要 JavaMail。我刚刚测试成功。

import javax.mail.internet.MimeUtility;

String s = "=?ISO-8859-1?Q?Merve_G=FCl?=";
String string = MimeUtility.decodeText(s);
