Inspired by the Sukhoi SU-30SM 2012-2013 paint scheme side numbers (that can be seen here: http://www.irkut.com/upload/information_system_15/9/9/4/item_994/information_items_property_1731.jpg

As Irkut Corporation/Russian Air Force used only few numerical digits (namely 0, 1, 2, 4, 5, 6 and 7) I designed the rest of the them, latin alphabet, cyrillic and a whole bunch of diacritics.
