DEC Special Graphics
DEC Special Graphics represents a 7-bit character encoding created by Digital Equipment Corporation, primarily utilized for rendering box-drawing symbols on the VT100 terminal and compatible emulator programs, as well as within various bulletin board systems. The ISO/IEC 2022 escape sequence ESC ( 0 (hexadecimal 1B 28 30) activates this character set by replacing the standard lower-case ASCII letters, while ESC ( B (hexadecimal 1B 28 42) restores the original ASCII. IBM designates this encoding as Code page 1090.
