Description:
------------
If you set the locale to 'lv_LV.UTF-8' and have the locale generated on your system, then the code below will return garbage as the 'thousands separator'. It displays ok for me when running with CLI SAPI

Reproduce code:
---------------
<?php
if (false !== setlocale(LC_ALL, 'lv_LV.UTF-8')) {
    $locale_info = localeconv();
    echo number_format(20000,0,$locale_info['decimal_point'], $locale_info['thousands_sep']);
}
?>


Expected result:
----------------
20 000

Actual result:
--------------
20&#65533;000

The "garbage" you get is a non-breaking space in UTF-8. You can always use utf_decode() on it:

<?php
if (false !== setlocale(LC_ALL, 'lv_LV.UTF-8')) {
    $locale_info = localeconv();
    echo number_format(20000,0,$locale_info['decimal_point'],
utf8_decode($locale_info['thousands_sep']));
}
?>

Since unicode support is coming in PHP6 and will not be addressed before, this is "wont fix" in earlier versions.

I suggest you really don't use setlocale() if you want to use UTF-8.
At least not for numbers.
