The page declares UTF-8 encoding (in a meta tag only - not really ideal, but
it works), though it seems to use mostly just Ascii characters, representing
other characters using character references like ’. Nothing wrong with
that really, but the author is not making the best possible use of UTF-8.

What GUI? I see no Graphic User Interface there. Just a web page. If you
view it using a graphic browser, then you are using a GUI, but that's a
different issue.

What? Where? I don't see anything like that on the page.

You're enigmatic.

The page has apostrophes written as ’, which is a correct reference,
and modern browsers render it well. They don't map it to ASCII apostrophe,
except perhaps if they need to work with an ASCII-only rendering situation.

I don't see what you mean by "this".

(HTML-Kit is an authoring tool, not a browser.)

Well it doesn't. The string ’ is rendered literally, as a mess of
characters. Maybe the actual file you used for testing contains something
completely different, though. (As usual, posting a URL...)
You have some confusion here. You have probably played with a program that
converts character references to UTF-8 encoded characters and later you have
interpreted the octets of the UTF-8 representation according to theWindows
Latin 1 (windows-1252) encoding.
It's easy to get confused with character encodings, and difficult to help
people out from a confusion. It's probably best to stop here and start
afresh. What do you really want? To use a punctuation apostrophe (’) on a
web page? Then write ’. Or ’, if that's easier to remember.
There are other ways too, but these methods work independently of character
encoding and don't make you confused and don't require any particular editor
or UTF-8 support in your authoring software.
