That's a question about UTF-8, not about Forth.  But fortunately, I
can use Forth to answer it:

First, let's look what this character looks like:

s\" \xe2\x80\x9e" type

and as output I see a lower double-quote (like ",,", but as one glyph;
maybe I should have written "double-comma" instead of "lower
double-quote"), which is used in German for starting quotes.  For
ending quotes, German uses an (upper) double-quote, not the same
character.  My guess is that whoever wrote the text you looked at
normally writes in German or in another language that uses the same
convention.

Next let's look at what more we can find out about this character.  To
look it up, we need the Unicode code point number:

s\" \xe2\x80\x9e" drop xc@ hex.

(Hurray, sometimes the Xchar words are useful after all:-).

The output is 201e, and googling for it leads me to

http://unicode.scarfboy.com/?s=U%2B201E

which tells me that the character name is "DOUBLE LOW-9 QUOTATION
MARK", contains additional info and points to other pages about this
character.

If you look at
http://www.utf8-chartable.de/unicode-utf8-table.pl?start=8192, you
also find opening and closing upper double-quotes (U+201C, U+201D),
and I often see these (I think; anyway, non-ASCII) quotes used in the
web instead of the universal ASCII double-quote.  I guess we are
seeing progress at work.
