See the output from the following line:
  perl -MEncode -e 'for (my $i=0; $i < 256; $i++){printf "%d:\t%s\t%s\t0x%s\t0x%s\n", $i, chr($i), encode("UTF-8", decode("iso-8859-1", chr($i))), unpack("h*", chr($i)), unpack("h*", encode("UTF-8", decode("iso-8859-1", chr($i))));}' | less

I use less as not all characters are nice to the terminal. On a full
8bit terminal that will output the latin1 char, the char after converted
to UTF-8 and the hex value of both. On a UTF-8 terminal that will most
likely not work (or perl tell you that ther is something wrong) or
simply don't show any in the first column as it cannot display all
octeds that can be in latin1.
