Yes, they're changing ISO 8859-7. It's in a *backwards* compatible
way, but that is incompatibility of a sort. People had assumed that
8859-x standards had fixed content forever, but nature and
standards committees abhor a vacuum, so those holes are starting
to get filled. This means that the previous version of 8859-7 and
the about-to-be-ballotted 8859-7:1998 will have at least four new
differences in characters:

U+20AC 0xA4 EURO SIGN
U+XXXX 0xA5 DRACHMA SIGN
U+037A 0xAA GREEK YPOGEGRAMMENI
U+037E 0xAE GREEK QUESTION MARK

And this will imply that there will need to be two MIME *charsets* -- one
for the old version and one for the new version.
