问题描述
String
可以这样描绘: @Override
public void paintComponent(Graphics g){
super.paintComponent(g);
Graphics2D g2d =(Graphics2D)g.create();
尝试{
g2d.setColor(Color.BLACK);
g2d.setFont(new Font(Serif,Font.PLAIN,12)); //日文字符是可见的
//g2d.setFont(new Font(Arial, (Berryz Kobo [情色摇滚])(MV)(日语字幕)(日语字母不可见)(仅限正方形)
g2d.drawString(Berryz工房「ROCKエロティック」 ,10,45);
} finally {
g2d.dispose();

$ b 问题是如果我做 g2d.setFont(new Font(Arial,Font.PLAIN,12));
- 日文字符不可见,只是正方形而已:
如果我设置字体像 g2d.setFont(new Font(Serif,Font.PLAIN,12));
- 一切工作正常:
但我想用 Arial
字体。也许我必须检测日文字符并切换到不同的字体,然后再回来?
解决方案它使用逻辑字体。 SANS_SERIF
在Windows上是Arial(主要)。

A String
can be painted like that:
@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();
}
}
The problem is that if I do g2d.setFont(new Font("Arial", Font.PLAIN, 12));
- Japanese characters are not visible, just squares instead:
And if I set font like g2d.setFont(new Font("Serif", Font.PLAIN, 12));
- everything works fine:
For example, in MS WordPad the characters are visible if Arial font is selected:
But I want to use Arial
font. Maybe I have to detect Japanese character and switch to different font, and then back again?
解决方案 It works using the logical fonts. SANS_SERIF
will be Arial (primarily) on Windows.
