Description:
------------
I am using the following code:

$locale = setlocale(LC_ALL, 'FRA');
$data   = localeconv();
$thousands_sep = $data['thousands_sep'];
$ascii = ord($thousands_sep);

The value in $ascii is 160 (?) when it should be 32 (space).

When I use this with number_format() the result is written to an XML file then transformed into HTML using XSL. The XSL transformation process fails because it is not valid UTF-8.



Reproduce code:
---------------
$locale = setlocale(LC_ALL, 'FRA');
$data   = localeconv();
$thousands_sep = $data['thousands_sep'];
$ascii = ord($thousands_sep);


Expected result:
----------------
ord($thousands_sep) should be 32 (space), not 160

Actual result:
--------------
ord($thousands_sep) is 160
