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

Question

A String can be drawn like this:

 @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:

And if I set the font as g2d.setFont(new Font("Serif", Font.PLAIN, 12)); - everything works fine:

For example, in MS WordPad, characters are visible if the Arial font is selected:

But I want to use the font Arial . Maybe I need to discover a Japanese character and switch to a different font, and then again?

Answer 1

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