Determining in Java whether a particular font can

问题:

Is there a way in Java to determine whether a particular font can render a particular character?

回答1:

Try

Font f = ... ; // you have your font
Character c = 'ن'; // Nun, N, in Farsi

if(!f.canDisplay(c)) {
    int gcode = f.getMissingGlyphCode();
    System.out.format("not supported.  Glyph code used: %d\n", gcode);
}

Take a look at this answer and the code link therein. Apparently there's a built-in Java/AWT function (in java.awt.font.*) that can access a font's glyph (by codepoint).
