Re: [Tiki-devel] A Unicode-aware replacement for the natcasesort() function

Hi Volker,

This is how tiki-check.php does it:

// intl
$s = extension_loaded('intl');
if ($s) {
 $php_properties['intl'] = array(
   'fitness' => tra('good'),
   'setting' => 'Loaded',
   'message' => tra("The intl extension is required for Tiki 15 and newer.")
 );
} else {
 $php_properties['intl'] = array(
   'fitness' => tra('unsure'),
   'setting' => 'Not available',
   'message' => tra("intl extension is preferred for Tiki 15 and newer.
Because is not available, the filters for text will not be able to detect
the language and will use a generic range of characters as letters.")
 );
}
