Bug #81390 [Com]: mb_detect_encoding() regression

Edit report at https://bugs.php.net/bug.php?id=81390&edit=1 ID: 81390 Comment by: alec at alec dot pl Reported by: alec at alec dot pl Summary: mb_detect_encoding() regression Status: Open Type: Bug Package: mbstring related PHP Version: 8.1.0beta3 Block user comment: N Private report: N New Comment: $test = 'test:test'; $encodings = array_diff(mb_list_encodings(), ['UUENCODE', 'wchar']); echo mb_detect_encoding($test, $encodings, true); returns HTML-ENTITIES, this makes no sense. Previous Comments: ------------------------------------------------------------------------ [2021-08-26 17:10:34] alec at alec dot pl Using $test = 'test:test' in the test script also will return UUENCODE. This is really wrong. ------------------------------------------------------------------------ [2021-08-26 17:03:35] alec at alec dot pl Description: ------------ The same code returns "ISO-8859-1" on PHP8.0 and "UUENCODE" on PHP8.1.0beta3. Note: the text contains some ascii with two 0x0EB characters Note: ISO-8859-1 is before UUENCODE in the mb_list_encodings() result. Note: Even removing UUENCODE from the list does not make it to return expected ISO-8859-1 Test script: --------------- $test = base64_decode('Q0hBUlNFVD13aW5kb3dzLTEyNTI6RG/rO0pvaG4='); echo mb_detect_encoding($test, mb_list_encodings()); Expected result: ---------------- ISO-8859-1 Actual result: -------------- UUENCODE ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=81390&edit=1
