Flash / Php charset problem?

Here’s the dilemma;

Flash pseudo code;
inputfield.restrict = “^”’";

US keyboard layout: All chars work apart from " and ';
UK keyboard layout: All chars work apart from @ and ';
(Because " is at the position of @ on UK keyboard?)

Now, standalone (url/file.swf) it works the correct way both US and UK. Inside a index.php, the UK keyboard blocks @ instead of ";

Why is this? It’s charset utf-8, properly validating XHTML 1.1 ? Any ideas? Here’s the header of the php file;


<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

Thanks. No idea whats going on…
