The DEC Special Graphics Character Set is one of the available character sets on VT100 and compatible terminals.
It differs from ASCII only in the 32 characters from code points (decimal) 95 through 126 (the "special graphics characters"). Its most recognizable characters are probably the line-drawing and box-drawing characters, which were frequently used in the VT100 variant of ANSI Art.
All of the characters exist in Unicode, though there does not seem to be an official mapping. The horizontal "scan" line characters were added in Unicode 3.2.0[1].
