All implementations must support a character repertoire called standard-char; characters that are members of that repertoire are called standard characters.
The standard-char repertoire consists of the non-graphic character newline, the graphic character space, and the following additional ninety-four graphic characters or their equivalents:

The graphic IDs are not used within Common Lisp, but are provided for cross reference purposes with ISO 6937/2. Note that the first letter of the graphic ID categorizes the character as follows: L---Latin, N---Numeric, S---Special.
