New Comment:
ASCII only encodes 128 characters. I think LOW/HIGH was meant to reference the non-printable
characters.

Doesn't FILTER_FLAG_ENCODE_HIGH contain the error here? 127 is lower ASCII.

Log: Fix #69203: FILTER_FLAG_STRIP_HIGH doesn't strip ASCII 127
------------------------------------------------------------------------

Description:
------------
FILTER_FLAG_STRIP_HIGH doesn't strip ASCII 127. This is inconsistent with
FILTER_FLAG_ENCODE_HIGH which encodes ASCII 127 as expected.
Test script:
---------------
// FILTER_FLAG_STRIP_HIGH
var_dump(filter_var("\x7f", FILTER_SANITIZE_STRING, FILTER_FLAG_STRIP_HIGH));
var_dump(filter_var("\x7f", FILTER_UNSAFE_RAW, FILTER_FLAG_STRIP_HIGH));
var_dump(filter_var("\x7f", FILTER_SANITIZE_ENCODED, FILTER_FLAG_STRIP_HIGH));
var_dump(filter_var("\x7f", FILTER_SANITIZE_SPECIAL_CHARS, FILTER_FLAG_STRIP_HIGH));
// FILTER_FLAG_ENCODE_HIGH
var_dump(filter_var("\x7f", FILTER_SANITIZE_STRING, FILTER_FLAG_ENCODE_HIGH));
var_dump(filter_var("\x7f", FILTER_UNSAFE_RAW, FILTER_FLAG_ENCODE_HIGH));
var_dump(filter_var("\x7f", FILTER_SANITIZE_ENCODED, FILTER_FLAG_ENCODE_HIGH));
var_dump(filter_var("\x7f", FILTER_SANITIZE_SPECIAL_CHARS, FILTER_FLAG_ENCODE_HIGH));
Expected result:
----------------
string(0) ""
string(0) ""
string(0) ""
string(0) ""
string(6) ""
string(6) ""
string(3) "%7F"
string(6) ""
Actual result:
--------------
string(1) ""
string(1) ""
string(3) "%7F"
string(1) ""
string(6) ""
string(6) ""
string(3) "%7F"
string(6) ""
