Charter BT family (Bitstream library) contains 20 fonts.
Bitstream Charter was designed in the mid-1980s by Matthew Carter. The typeface was designed with the limitations of low- and middle-resolution output devices in mind; hence the squared off serifs and lack of excessive diagonals and curves. The design, however, became an instant success on its own merits. It is an excellent everyday typeface for a wide variety of uses including books and technical manuals. Charter offers small cap, extension and alternate typographer sets that help to make it more versatile and functional.
ITC bought the Charter designs in 1993. Bitstream retains the right to sell the original designs.
