// setup STATIC variables

// in Unicode we would have two ways to do this:
// 1) we can use the standard greek characters (lowercase from 0x03B1 to
//    0x03C9; uppercase from 0x0391 to 0x03A9)
// 2) we can use the greek mathematical characters which range from
//    0x1D6A8 to 0x1D6DA. As you can see, these solution requires the use
//    of the UTF32 standard.
// since the 2nd solution is the harder way (because of UTF32 and the lack
// fonts which implement all those gliphs) even if it would be the most
// correct one, we'll use the first way.
//
// note: the final sigma characters (0x03C2 and 0x03A2) won't be used in the
