Everything up to 32 on this list is derived from someplace other
than 8859 and is not part of Latin-1, which consists solely of graphic
characters.
The standards which defines the control characters commonly employed in
the C0 space (0x00 - 0x1F) and the C1 space (0x80 - 0x9F) are defined by
"ISO/IEC 6429:1992 Information technology - Control functions for coded
character sets" and by "ISO 2022:1986 Information processing - ISO 7-bit
and 8-bit coded character sets - Code extension techniques". The former
defines things like NULL, HT, CR, LF, while the latter defines the semantics
of ESC.
