文本字段阿拉伯语输出显示奇怪的字符javaFX

Question

我正在使用javaFX开发一个桌面应用程序，我正在使用场景生成器版本11来创建包含TextFields和ChoiceBox的界面，我的输入应该设置为阿拉伯语。问题是，当我从TextFiled或ChoiceBox中检索文本并在控制台中打印时，它会显示这样的字符"；"；它还产生了一个将输入存储在数据库中的问题，这就是SQLException：java.sql.SQLSyntaxErrorException：您的sql语法中有一个错误；查看您的MariaDB服务器版本对应的手册，以了解在"附近使用的正确语法

当我尝试另一个没有场景构建器的项目时，我得到了正确的阿拉伯语输出，场景构建器可能是问题的根源吗？

这是我的fxml文件：

我可以找到一个解决方案，在运行程序之前，我首先用F9键编译它，然后用组合键SHIFT+F6运行它
