For characters that are part of ASCII, the UTF-8 encoding is identical, so nothing changes. For characters that are not part of ASCII, the UTF-8 codes have no representation in ASCII. Therefore, what you ask is either trivial or impossible.

"The phrase ANSI character set has no well-defined meaning..." Do you mean Windows-1252? Or do you mean some other ANSI standard such as ASCII or its successor ISO-8859? Perhaps http://reference.wolfram.com/language/ref/$CharacterEncodings.html would help you.
