From Pyrus N.A.:
FontLab Studio 5 is our classic font editor for macOS and Windows. It has been used by Adobe, Apple, IBM, Microsoft, Monotype, Morisawa and almost every other major font foundry in the world. It is the comprehensive solution for font foundries, professional type designers, typographers and graphic design studios, allowing them to design typefaces and create or modify fonts. FontLab Studio 5 offers a complete integrated workflow for font creation, from font family management, through multilingual glyph design and spacing and kerning, all the way to automatic and manual hinting and Python scripting. It supports outline font formats from OpenType and TrueType to PostScript Type 1, including Multiple Master fonts--a precursor to making OpenType Variable Fonts.
