将HTML字符代码转换为Java中的字符

我们的XML Feed在ISO-8859-1文件中提供了编码的UTF-8字符。这被送入数据库。所以文本是ISO-8859-1编码，并包含以下内容：

Our XML feed gives us encoded UTF-8 characters inside ISO-8859-1 a file. This is being fed into the database. So the text is ISO-8859-1 encoded and contains following stuff:

金融市场

有没有办法将其转换成普通的Java字符串？类似于：

Is there a way to convert that into a normal Java string? Similar to:

String str = fromHtmlUtf8("金融市场");

其中结果的str将包含正常的UTF8字符。中国人在这种情况下，但可以相当混合。

Where resulting str will contain normal UTF8 chars. Chinese in this case, but can be quite mixed.

谢谢。
