The above is probably the best way to find out what it is; if you want
to delete all instances of it, one way that has worked for me in the
past is:

* Put the cursor on the character
* Press y<space> to "yank" it into the unnamed register
* Type :%s/<C-R>"//g (where <C-R>" means press Ctrl & R together and
then press shift-2 or whatever combination on your keyboard gives a
double-quote) - this pulls the unnamed register content into the
command line

You can also use the output of g8 with:

%s/\%uXXXX//g (where XXXX is the hex code shown by g8) - see :help \%u
