Just to out-pedant you, I'll point out that what most people would think
of as a "character" is neither a byte nor a code point, but a grapheme,
so I would say *none* of the answers on that page is correct.
$string = 'Zoë'; // "Zoe\u{0308}" not "Zo\u{00EB}"
var_dump(substr($string, -1));
var_dump(mb_substr($string, -1));
var_dump(grapheme_substr($string, -1));
string(1) "�"
string(2) "̈"
string(3) "ë"
