Looks like that #41067 https://bugs.php.net/bug.php?id=41067 was not fully
fixed.

Description:
------------
It's a typical case the JSON *and* UTF-16 specifications warn about: decoding of
non-existing UTF-16 code-points:
json_decode('"\ud834"')
shoud give NULL because \ud834 is *invalid*. But instead it starts some party,
get's boozed and offers this as UTF-8 byte-sequence:
1110 1101 1010 0000 1011 0100
1110 xxxx 10xx xxxx 10xx xxxx
1101 1000 0011 0100
D8 34
U+D834 is not a valid unicode character.
Test script:
---------------
if (NULL !== json_decode('"\ud834"')) {
echo "json_decode is still broken.";
}
Expected result:
----------------
NULL because the json is invalid.
Actual result:
--------------
PHP tries to create UTF-8 out of it and fails by creating invalid UTF-8 unicode
byte-sequences.
