应用中的Unicode字符无法正确显示

Question

例如,如何转换字符串"Bohinjska ?ešnjica".我从网站获得的字符串,它没有编码unicode.它在使用swing(Netbeans)的程序中工作正常,但是当我通过jar到Windows控制台的链接(运行jframe应用程序)时,它不会在字符串中显示正确"Bohinjska ?ešnjica"的字符'?'和字符'š'.

String example="Bohinjska ?ešnjica";

我从网站上获取该字符串.如何编码或显示,因为它是("Bohinjska ?ešnjica")在一个Swing应用程序,所以当我将运行一个jframe应用程序,它会显示我这个角色(以及其他Unicode字符ofcourse("Z","Z","C"和"S") )？

链接1:我的程序的jar文件从控制台 链接2 运行:当我从netbeans运行程序时

阅读网站上的内容:

             URL nov = new URL("http://www.arso.gov.si/vreme/napovedi%20in%20podatki/vreme_avt.html");
            URLConnection conn = nov.openConnection(); //connect to a   website
            BufferedReader br = new BufferedReader(
                    new InputStreamReader(conn.getInputStream()));
            String inputLine;
            StringBuilder niz = new StringBuilder(); 
            while ((inputLine = br.readLine()) != null) {
                String vrstica = inputLine.trim(); //reading html...

}

在运行时,我们可以Font.canDisplayUpTo(String)用来确定哪些已安装的字体可以显示给定的文本.逻辑字体,例如Font.SANS_SERIF并且Font.SERIF通常由其他字体组成,并且可以覆盖大量不同的脚本.

以下是使用给定文本的示例,其结果显示在此计算机上.

顺便说一句 - 谷歌翻译告诉我这是斯洛文尼亚语而不是克罗地亚语,但幸运的是,完全相同的技术适用于任何脚本.
