Answer 1

Lazy version:

Arrays.asList(GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames()).contains(FONT_NAME)

Answer 2

java.awt.GraphicsEnvironment.getAvailableFontFamilyNames() can give you a list of the available fonts installed on the current system. You could also use java.awt.GraphicsEnvironment.getAllFonts() to get java.awt.Font objects.

Then, you can use java.awt.Font.canDisplay(int) to check whether a Unicode character can be displayed in that font (where the int is the integer representation of the multibyte character).
