Stanford/ITS character set is an extended ASCII character set based on SEASCII with modifications allowing compatibility with 1968 ASCII.
It is used as an alternate character set of the SUPDUP protocol for terminals with %TOSAI and %TOFCI bits set. It is also recommended for TeX implementations on systems with large character sets. The default plain TeX macro package sets values (↑) and (↓) as alternative character codes for superscripts and subscripts, respectively (the default being ^ and _).
The Knight keyboard is an example of a keyboard capable of inputting all of the defined characters excluding ⋅γδ±⊕◊∫, as they are mapped to ASCII commands NUL, HT, LF, FF, CR, ESC and DEL, respectively.
Each character is encoded as a single seven-bit code value. It contains all 95 printable ASCII characters along with 27 mathematical symbols and 6 Greek letters.
