The current message can be mistaken, if the reader does not READ, if
it is asking a yes/no question, but with the "default" label, you
cannot imagine answering "yes", which is clearly not one of the
things in the same class as "UTF-8" that is given as the default,
which also serves as an example.

This is indeed a clever hack (not hack on computer code but hack on
the mind of human who is reading the message).

Agreed on the first half of the statement, if we have an easy and
portable way to tell if a given random string names a valid charset.
I do not recommend to "fall back" to anything, if we are asking an
input from the user.

Thanks.
