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?
It works using the logical fonts. SANS_SERIF
will be Arial (primarily) on Windows.
