      public Kern(int[] firstGlyphCodes, int[] secondGlyphCodes, UnicodeRange[] firstUnicodeRanges, UnicodeRange[] secondUnicodeRanges, float adjustValue)
      Creates a Kern object with the given glyph arrays and kerning value. The first and second sets of glyphs for this kerning entry consist of the union of glyphs in the glyph code arrays and the unicode ranges.
      Parameters:
      firstGlyphCodes - An array of glyph codes that are part of the first set of glyphs in this kerning entry.
      secondGlyphCodes - An array of glyph codes that are part of the second set of glyphs in this kerning entry.
      firstUnicodeRanges - An array of unicode ranges that are part of the first set of glyphs in this kerning entry.
      secondUnicodeRanges - An array of unicode ranges that are part of the second set of glyphs in this kerning entry.
      adjustValue - The kerning adjustment (positive value means the space between glyphs should decrease).
