下面是我的代码，它打算获取两个.ckl文件，比较两个文件，添加新项目并创建一个新的合并文件。该程序在Netbeans中运行时可以正确执行，但是，当执行.jar时，该程序似乎未使用UTF-8编码文件。我对编程很陌生，想知道在什么地方或如何执行这种编码？

**我删除了Swing代码和其他行，以便仅显示我的方法，该方法完成所有比较和合并。

// Going in a different direction. We are using a couple booleans to tell us when we want to copy or not. So at the beginning since we start

// we set the boolean to false so that we dont start copying anything from the second file until it is a vuln. We set to true when we see vuln

// and set it to false if we already have that in our list.

// We have a tmpCopy to store away the value of copy when we see a vuln, and reset it to that value when we see an
