Stanford/ITS character set is an extended ASCII character set based on SEASCII with modifications allowing compatibility with 1968 ASCII.[2]
It is used as an alternate character set of the SUPDUP protocol for terminals with %TOSAI
and %TOFCI
bits set.[2] It is also recommended for TeX implementations on systems with large character sets.[1] The default plain TeX macro package sets values B16 (↑
) and 116 (↓
) as alternative character codes for superscripts and subscripts, respectively (the default being ^
and _
).[3]
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.
