java - 来自 JTextField 的波兰语字母

Question

如何从 JTextField 或 JTextArea 获取带有波兰字母的 String？当我使用 myTxtArea.getText() 并且在我的 JTextArea 中时，我得到了 ĄĆĘŁŃÓŚŹŻąćęłńóśźż 它只识别 ?????Ó ????????ó???。

来自 JTextField 和 JTextArea 的文本将保存在 *.txt 文件中

这是我的代码:

import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.IOException;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class MyAppCreateAcc {

public static void main(String[] args) throws IOException {
        AppGUI ag = new AppGUI();
    }
public MyAppCreateAcc() throws IOException {

    String group = AppGUI.getGroup().getText();

    String[] lines = AppGUI.getNote().getText().split("\\n");

    BufferedWriter w = new BufferedWriter(new FileWriter(
            "zaloz_konta.cmd"));
    w.write("mode con codepage select=1250");
    w.newLine();

    for (int j = 0; j < lines.length; j++) {

        /*
         * delete more than one space between words and from the full name
         * create a short one first letter of name and surname after all
         * lowercase like on example: John Smith = jsmith
         */
        if (lines[j] == null || lines[j].equals("")) {

            // if there is a gap between the names do nothing

        } else {
            lines[j] = lines[j].trim().replaceAll(" +", " ");
            Pattern pattern = Pattern.compile("\\s([A-Za-z]+)");
            Matcher matcher = pattern.matcher(lines[j]);
            String shortName = "";
            if (matcher.find()) {
                shortName = (lines[j].charAt(0) + matcher.group(1))
                        .toLowerCase();
            }

            w.write("call konto.cmd " + shortName + " \"" + lines[j]
                    + "\" 123 " + "\"" + group + "\"");
            w.newLine();
        }
    }
    w.close();
}

}

我只想从以下位置获取波兰语字母:

String[] lines = AppGUI.getNote().getText().split("\\n");

JTextCompoents使用

• JTextComponent.write()用于输出到 FileIO

• JTextComponent.read()用于从 FileIO 加载数据

默认接受分隔符和文件编码页面
