Keld - I'm not sure whether I understand you correctly. A lot of
"charset"s contain control characters, such as ESC, but in MIME
terms ESC is actually a control octet, and not a character.
For example, the ESC in iso-2022-jp is such a control octet,
but it is used to switch between coded character sets. It appears
in the "series of octets", but not in the "sequence of graphic

Or is it something else that you had in mind?
