+- **VFB** (FontLab, proprietary format, not buildable with gftools): Quantico-Bold-OTF.vfb, Quantico-BoldItalic-OTF.vfb, Quantico-Italic-OTF.vfb, Quantico-Regular-OTF.vfb
+- **SFD** (FontForge, not buildable with gftools-builder): Quantico-Bold-TTF.sfd, Quantico-BoldItalic-TTF.sfd, Quantico-Italic-TTF.sfd, Quantico-Regular-TTF.sfd
