How to use regular expression to match case insensitive unicode character?

I'm trying to use regular expression with php to match both upper case and lower case unicode character.

Here is my example code:

$s = "a à À";
$s = preg_replace("/à/iU", "a", $s);
echo $s;

But didn't success, anyone can help?

This works:

$s = "a à À";
echo preg_replace('/à/iu', "a", $s);

Output:

a a a

Use /u not /U flag for unicode characters in your regex. U is for un-greedy (lazy) matching.
