  AYS?  I thought the problem was just this:

  Does that mean there's no way to explicitly specify plain ASCII encoding?
Or does it mean you have to use iso-8859-whatever-it-is or one of the codepage
based names?

  Well, we've had to deal with all the teething troubles, and it seems not to
have been too hard, and I was under the impression we weren't the only
platform to have done this; e.g., from Markus Kuhn's "UTF-8 and Unicode FAQ
