如何在XMLParser.java中将ANSI转换为UTF-8

Question

我使用XMLParser从网址中检索数据但文本错误。

ANSI => ERROR, UTF-8 => SUCCESS

如何在XMLParser.java中将ANSI转换为UFT-8

文字示例：

Những sét Súng MG cực HOT của LK.Lang-Kinh

Url xml：

http://truyenucnon.com/thanh.xml

文字错误在我的应用中（默认ANSI）：

Những sét Súng MG cực HOT của LK.Lang-Kinh

文字成功UTF-8：

Những sét Súng MG cực HOT của LK.Lang-Kinh

尝试在您的网站访问中使用charset：

xml = EntityUtils.toString(httpEntity, Charset.forName("utf-8"));
