/**
 * Create a scaled {@code Font} which can display all characters
 * inside the given text string.
 * This is mostly necessary for the header font. Thats because the currently
 * used ShadowedBlack is missing support for CJK and others. Even some
 * special glyphs for European languages like the triple-dot are missing.
 * 
 * @param string The text to find a compatible font for.
 * @param fontType How the font should look like.
 * @param fontSize Its relative size.
 * @param style The font style for choosing plain, bold or italic.
 * @param scaleFactor The applied scale factor.
 * @return The created Font.
