You'll need to find the unicode values for the specific characters you need (see
www.unicode.org), but I will give you an example.
The unicode value for the Greek capital theta is 0398. To display this character in Java:
(where x and y are the coordinated at which you wish to draw the
string)
This would display the string "This is theta: " followed by a theta symbol.
The "\u" basically tells Java to take the value of the next four characters in the string and convert them into a unicode character.
