Yes, it it locale dependent. If I prepend script with 'setlocale(LC_ALL, "C")',
everything works correctly. But if I don't (my default locale is ru_RU.UTF-8) or if I
explicitly use 'setlocale(LC_ALL, "ru_RU")', result is incorrect.

I can't demonstrate it at 3v4l.org as it does not support required locales.

I can't reproduce this behavior, see <https://3v4l.org/QZJSC>.
Maybe it's locale dependend?

Description:
------------
When escape character set for str_getcsv() is followed by some UTF characters, string is parsed
incorrectly.

I tested it on php 5.4, 5.5, 5.6 and 7.0 - behavior is the same.

Test script:
---------------
$utf_1 = chr(0xD1) . chr(0x81); // U+0440;
$utf_2   = chr(0xD8) . chr(0x80); // U+0600

$string = '"first #' . $utf_1 . $utf_2 . '";"second one"';
$d = str_getcsv($string, ';', '"', "#");

print_r($d);



Expected result:
----------------
Array
(
    [0] => first #с؀
    [1] => second one
)


Actual result:
--------------
Array
(
    [0] => first #с؀";second one"
)
