使用方法 drawString(..) 使用 Arial 字体绘制日文字符 (Graphics2D)

Painting Japanese characters using Arial fonts with method drawString(..) (Graphics2D)

一个String可以这样画:

@Override
public void paintComponent(Graphics g) {
    super.paintComponent(g);
    Graphics2D g2d = (Graphics2D) g.create();

    try {

        g2d.setColor(Color.BLACK);

        g2d.setFont(new Font("Serif", Font.PLAIN, 12));//Japanese characters are visible
        //g2d.setFont(new Font("Arial", Font.PLAIN, 12));//Japanese characters are not visible (squares only)

        g2d.drawString("Berryz工房 『ROCKエロティック』(Berryz Kobo[Erotic ROCK]) (MV)", 10, 45);

    } finally {
        g2d.dispose();
    }
}

问题是如果我这样做 g2d.setFont(new Font("Arial", Font.PLAIN, 12)); - 日语字符不可见,只有正方形:

如果我将字体设置为 g2d.setFont(new Font("Serif", Font.PLAIN, 12)); - 一切正常:

例如,在 MS 写字板中,如果选择 Arial 字体,则字符可见:

但是我想用Arial字体。也许我必须检测日文字符并切换到不同的字体,然后再返回?

它使用逻辑字体工作。 SANS_SERIF 将在 Windows 上(主要)使用 Arial。
