OpenType has become the new industry standard font format, offering countless new creative options to everyone working with type. Type designers have been freed from the shackles of PostScript's restrictive character set, enabling them to include alternates, small caps, swashes, ligatures and additional languages within one single feature-rich (Pro) font.
Furthermore, fonts can be 'programmed' to behave contextually, automatically inserting a stylistic alternate, ligature or end glyph into OT-savvy applications when the relevant feature is activated.
