[RESOLVED] regex:range out of order

[Deathmanlp]

<?php
$pattern="#[x\{0410}-x\{042F}]#u";
$string="&#1040;&#1060;";
echo preg_match ($pattern,$string);
?>

$pattern should match any capital Cyrillic letters

However I get this error
preg_match(): Compilation failed: range out of order in character class at offset 10 in /home/ge0rgi/www/preg.php on line 4
Any ideas ?

What is "x{0410}" supposed to represent? As it stands, it represents: the letter 'x', followed by a '}' (which was unnecessarily escaped), followed by the digits '0410', followed by a '}' brace.

Perhaps you meant "\x{0410}" instead?
