Description Rob McKay CLA 2007-04-05 06:38:12 EDT 
Currently there is no way to check if a character is defined for a given font.
There should be an API similar to the AWT Font.canDisplay(char c) or Font.canDisplay(int codePoint) methods.

I know this is a dup but can't find it.

Some code to check if a glyph exists for a given char

Here is some (windows) code which could be added to the Font class to check if a char has a glyph.  It seems to work but there are probably better ways of doing it since it continually allocates windows objects which could probably be cached.

I've found the duplicate after a lot of searching. It is 32120 - SWT Font or FontData should provide a method to query available glyph.
