These references do not show ASCII, but eg CP437 (standard DOS Codepage)

CP437 consists of:
0-127: standard ASCII
128-255: cp437 extension to ASCII

Almost all codepages differ only in the high ascii range.

eg cp850 (equivalent to iso-latin-1 in dos) consists of ASCII+cp850
extension ...

There IS :)
(if not than you have a really bad reference ... :)

I still can't see the problem ...

There are rules and these rules are accepted ...

No ... the rest depends on the codepage you use ...
They are also standardized. (mostly :)

No ... absolutely not.

The Email consists of the values ...

and a line telling HOW TO INTERPRET THEM ...
(characterset latin-1, cp437 ...)

If you know what codepage the sender was using, you can show the characters
on your system correctly as well ...)

There is a standard for most european languages.
(iso-latin-1 ...)

 SH> Other languages may simply use some other system.
Exactly .. and this is how it works ....
for example there are 2 hungarian characters missing from latin-1, so
there's iso-latin2 containing all hungarian characters ....
