You already have it. Any font which supports Unicode will be supported in the same way in all similar applications, as well as in your regular and rich text boxes, labels and text boxes.
If you're interested in a font which would support the most rich set of different Unicode sub-ranges, you can use "Arial Unicode MS". There is also very good Open Source monospace font (just for programmers); it's name is "Anonymous Pro".

(Please forgive me if I did not understand this question correctly; unfortunately, the wording is rather poor, so the question is not very clear, as Sandeep (who usually understand unclear text much better than I do) noticed in his comment. Please clarify so I could improve my answer if so is needed.)
Best,
