> Why you want to give simple but misleading name?

I suppose the only reason is because of examples like this:

>> File.binread('picture.jpg').encoding
=> #<Encoding:ASCII-8BIT>

(there's not much ASCII about most of those jpeg bits, so, for me, the
encoding name assigned it is a bit misleading).

> I want developers to read document when they meet ASCII-8BIT.

So you want developers to realize that they can grep it "as if" ASCII, correct?
That is a good idea.

Maybe something like the name ASCII-8BIT-COMPATIBLE would satisfy both?

Thanks.
