Bug #81366 [NEW]: mb_detect_encoding behaving different and failing to detect UTF-8
From: martin at herndl dot org
Operating system: macOS
PHP version: 8.1.0beta2
Package: mbstring related
Bug Type: Bug
Bug description:mb_detect_encoding behaving different and failing to detect UTF-8
Description:
------------
mb_detect_encoding with ommited encodings (= null as argument =>
fallback to default detect order) behaves different on 8.1.0beta2 and
fails to detect UTF-8 in some cases with out-of-the-box settings.
I noticed this via the
ApplicationTest::testRenderExceptionWithDoubleWidthCharacters test
from Symfony in https://github.com/symfony/symfony/issues/41552
that
broke because it converted UTF-8 to UTF-8 again.
Test script:
---------------
<?php
var_dump(mb_detect_order());
var_dump(mb_detect_encoding('ã³ãã³ãã®å®è¡ä¸ã«ã¨ã©ã¼ãçºçãã¾ããã',
null, true));
var_dump(mb_detect_encoding('ã³ãã³ãã®å®è¡ä¸ã«ã¨ã©ã¼ãçºçãã¾ãã',
null, true));
Expected result:
----------------
array(2) {
[0]=>
string(5) "ASCII"
[1]=>
string(5) "UTF-8"
}
string(5) "UTF-8"
string(5) "UTF-8"
Actual result:
--------------
array(2) {
[0]=>
string(5) "ASCII"
[1]=>
string(5) "UTF-8"
}
string(5) "ASCII"
string(5) "UTF-8"
