CODE(c)
c: character
c must be a valid CP1252 (Windows-1252) character.
CP1252 (Windows-1252) is also known as the "ANSI code page", but it is not an ANSI standard.
CP1252 (Windows-1252) is based on an early draft of ISO-8859-1, and contains all of its printable characters (but partially at different positions.)
This function is Excel compatible.
In CP1252 (Windows-1252), 129, 141, 143, 144, and 157 do not have matching characters. For x from 1 to 255 except 129, 141, 143, 144, and 157 we have CODE(CHAR(x))=x.
