Total 12 Separate Font Files for the alternate.
If you works with a program that not support OpenType Features (Photoshop CS, Inkscape, Xara, CorelDraw, etc), i provide the alternates font in TTF Format and you must install all the fonts. NO NEED to open the characters map or Fontsbook with PUA Unicode.
But if you are work with a program that support Fully OpenType Features ( Illustrator, InDesign, Photoshop CC, ), you only have to install one single font file Jibriel in OTF format, all the glyphs are in there. You can access all the alternates through the glyphs pallette.
