PHP version: 5.1.6
PHP Bug Type: Program Execution
Bug description: Wrong character encoding from external program output
Description:
------------
PHP is assuming character encoding from external executed svn client, as
ASCII.
Even when external program returns ISO-8859-1 encoded string, PHP "parses"
the encoded string as ASCII, expanding accented characters as literal
string form and not their binary form.
For example:
an output like "Acentuação" turns to be a string in literal form
"Acentua?\195?\167?\195?\163o/".
Reproduce code:
---------------
Import some accented file or folders into a subversion repository. Is it
possible to convert the output to utf-8 using the command bellow:
# svn list 'file:////home/svn/herbert/' | iconv -tutf-8
But not when from PHP:
<?php
$cmd = "svn list 'file:////home/svn/herbert/'";
$out = shell_exec($cmd);
$res = unpack('c*', $out);
var_dump($res);
?>
var_dump reports:
array(29) {
[1]=>
int(65)
[2]=>
int(99)
[3]=>
int(101)
[4]=>
int(110)
[5]=>
int(116)
[6]=>
int(117)
[7]=>
int(97)
[8]=>
int(63)
[9]=>
int(92)
[10]=>
int(49)
[11]=>
int(57)
[12]=>
int(53)
[13]=>
int(63)
[14]=>
int(92)
[15]=>
int(49)
[16]=>
int(54)
[17]=>
int(55)
[18]=>
int(63)
[19]=>
int(92)
[20]=>
int(49)
[21]=>
int(57)
[22]=>
int(53)
[23]=>
int(63)
[24]=>
int(92)
[25]=>
int(49)
[26]=>
int(54)
[27]=>
int(51)
[28]=>
int(111)
[29]=>
int(47)
}
So it's not possible to convert the string to other character set, since
it's invalid.
Expected result:
----------------
It's expected to PHP store the string as it's original binary format.
array(10) {
[1]=>
int(65)
[2]=>
int(99)
[3]=>
int(101)
[4]=>
int(110)
[5]=>
int(116)
[6]=>
int(117)
[7]=>
int(97)
[8]=>
int(-25)
[9]=>
int(-29)
[10]=>
int(111)
}
