Swing中汉字变成方框问题的解决方法

问题产生原因：
当前使用Java虚拟机在Win2000下显示字体不正确，出现点阵字体。具体原因是Java在改平台下找字体文件出错导致使用默认的西方代码字符集。

解决办法：
如果您能在您安装tbcs的盘下面找到目录.ZAC_JRE_WIN，则表明您没有安装自己的Java虚拟机。这个目录是个隐藏目录。进入目录lib，按照以下方法修改font.properties.zh文件和font.properties.zh.NT4.0文件:
1、查找字符串 filename./u5b8b/u4f53
将filename./u5b8b/u4f53 ＝ SIMSUN.TTF修改为filename./u5b8b/u4f53=SIMSUN.TTC,如果已经是filename./u5b8b/u4f53=SIMSUN.TTC则修改文filename./u5b8b/u4f53 ＝ SIMSUN.TTF。
2、替换所有 WingDings,SYMBOL_CHARSET,NEED_CONVERTED 为 /u5b8b/u4f53,GB2312_CHARSET
3、替换所有 Symbol,SYMBOL_CHARSET,NEED_CONVERTED 为 /u5b8b/u4f53,GB2312_CHARSET

如果您的机器上安装了自己的虚拟机（请确认您是否运行过JDK*.exe文件安装虚拟机），在您的Programe Files目录里面找到JavaSoft目录，在下面找到JRE/1.2/lib目录，按照以上修改方法修改font.properties.zh文件和font.properties.zh.NT4.0文件。再在您的Jdk目录下面找到jre/lib目录，修改相同文件名的文件。

如果嫌麻烦，将以下文本全部覆盖两个文件即可
