+// usual fallback methods when building against the 10.7 sdk or lower.
+// The 10.8 SDK added a function to let it find the correct fallback font.
+// If this fallback is not properly loaded, some characters may fail to
+// render correctly.
+//
+// Solution: If building with the 10.7 SDK or lower and the user's platform
+// is 10.9 or higher at runtime, substitute the correct font. This needs to
+// happen before the QApplication is created.
