使用英文版eclipse保存代码，出现some characters cannot be mapped using "Cp1251" character encoding.

some characters cannot be mapped using "Cp1251" character encoding.

解决办法：
方案一: eclipse->Window->Preferences->General->Content Types->Text->Java Properties File设置Default encoding,把ISO-8859-1改为UTF-8  然后update.

 方案一没有解决，直接点击图片中第二个button，解决！
