Well, documentation says "one character", what is misleading.

Description:
------------
Separator can be only one character that is not multibyte.

if setlocale is utf8, it cant parse the csv:
https://3v4l.org/MiD3B

if setlocale is not utf8, it parses the string, but the result has the 2 additional bytes:
https://3v4l.org/ohc4Q

Test script:
---------------
setlocale(LC_CTYPE, "en_US.UTF-8");

$test = "❤";

$line = "test1❤test2❤test3";
$header = str_getcsv($line, $test);
var_dump($header);

Expected result:
----------------
array(3) {
  [0]=>
  string(5) "test1"
  [1]=>
  string(7) "test2"
  [2]=>
  string(7) "test3"
}

Actual result:
--------------
array(1) {
  [0]=>
  string(21) "test1❤test2❤test3"
}
