There is not such a thing as "8 bit ascii". ASCII is defines 0-127. You
are probably refering to Latin-1/ISO8859-1 encoding, a (western
european) superset of ASCII, using 0-255. In fact, there are a lot of
different encodings using 0-255, most of them compatible in the ASCII
range 0-127, but with different meaning in the 128-255 range.

UTF-8 is actually a superset of ASCII, too. That is, an ASCII string is
a valid UTF-8 string.

(Read second paragraph, and
<http://en.wikipedia.org/wiki/Utf-8#Advantages> )

ANY modern spec MUST support UNICODE, and utf-8 is a practical and
convenient way to do it.
