Description:
------------
I was evaluating the mbstring extension because of its capabilities to
filter and convert input parameter to the correct encoding. During my
test I found out that an ISO-8859-1 string which ends with an an
accented character is wrongly detected as UTF-8, even if it ends with
an incomplete multibyte character (using iconv to convert the string
raises such notice).
Also reproduced with PHP 4.3.11 on FreeBSD 4 and 5.0.2 on Win32.
Reproduce code:
---------------
<?php
error_reporting(E_ALL);
mb_detect_order('ASCII,UTF-8,ISO-8859-1');
// \xE0 is ISO-8859-1 small a grave char
test_bug("Test: \xE0");
test_bug("Test: \xE0a");
function test_bug($s) {
echo "Trying: ";
var_dump($s);
iconv('UTF8', 'UCS2', $s);
echo "Detected encoding: ".mb_detect_encoding($s)."\n";
echo "Converted string:";
var_dump(mb_convert_encoding($s, 'UTF-8',
'ASCII,UTF-8,ISO-8859-1'));
echo "\n";
}
?>
Expected result:
----------------
Trying: string(7) "Test: à"
Notice: iconv(): Detected an incomplete multibyte character in input
string in test.php on line 13
Detected encoding: ISO-8859-1
Converted string:string(8) "Test: Ã "
Trying: string(8) "Test: àa"
Notice: iconv(): Detected an illegal character in input string in
/var/www/mbstring/test.php on line 13
Detected encoding: ISO-8859-1
Converted string:string(9) "Test: Ã a"
Actual result:
--------------
Trying: string(7) "Test: à"
Notice: iconv(): Detected an incomplete multibyte character in input
string in test.php on line 13
Detected encoding: UTF-8
Converted string:string(6) "Test: "
Trying: string(8) "Test: àa"
Notice: iconv(): Detected an illegal character in input string in
/var/www/mbstring/test.php on line 13
Detected encoding: ISO-8859-1
Converted string:string(9) "Test: Ã a"
