The Leksah IDE for Haskell has an interesting "candy" feature which renders certain operators like == as special symbols (a triple equals sign in this case). On OS X (Mountain Lion, 10.8.2, if it matters), these special symbols just show up as boxes. Googling reveals that others have had this issue but I couldn't find any solutions.
Does anybody know how to make the candy fonts work correctly in Leksah on OS X?
