Nickel probably uses a defined list of fonts at buildtime and register them with
http://doc.qt.io/archives/qt-4.8/qfo...pplicationFont. For sideload content they scan a given directory with
http://doc.qt.io/archives/qt-4.8/qdiriterator.html and try to load as many (valid) ttf/otf fonts as present in that folder.
So adding new fonts to the same folder won't work as expected.
