Well, there you have it, your basic misconception.

Sometimes, when that's practically meaningful, people use the name of a language 
to refer to both, as whoever it was did up-thread.

Or, they might mean just the latter. :-)

Apply some intelligence and it's all clear.

Stick boneheadedly to preconceived distinctions and absolute context independent 
meanings, and statements using other meanings appear to be meaningless or very 
unclear.

PS: You might, or might not, benefit from looking up Usenet discussions on the 
meaning of "character code", which is classic case of the confusion you have 
here. There's even a discussion of that in some RFC somewhere, I think it was 
MIME-related. Terms mean different things in different *contexts*.
