Hi Harlan,
Thank you for your thoughtful response. With the benefit of your
suggestions, I came to realize that the problem was my using a screen-
capture of web page. Following are details of my new understanding:

Thank you very much for this link. I like it's explantion of various
encoding schemes.
When I first saw this â?T string on the subject web page, I saved
the
page's image as a text file and opened that file in a hex editor.
That's
how I discovered their hex representation E2 80 99.
Now that you mention Unicode encoding, I went back and looked at the
web
page's source. It shows that the author coded the entity ’,
which
yielded that apostrophe. When I search for that entity, it asks "Are
you
looking for Unicode character U+2019: RIGHT SINGLE QUOTATION MARK?".
That
makes sense because 0x2019 == 8217. So, the author was trying to
present a
"high-class" apostrophe rather the common-place 0x27 ('). Finally,
now
that I look at that web page more carefully, I see that it *does*
present
the high-class apostrophe.
The last piece of the puzzle is that when I capture the textual
representation of the webpage with a "screen grabber" (SnagIt), it
somehow
comes up with that weird three character string.
The bottom line is that I violated the implicit boundaries between
various
tools and technologies. I apologize for that ;-)
Again, thank you for giving me some way to understand what was going
on
here, and especially for that helpful link.
