unicode question

[Anon]

Dear all
I am building up a forum (phpbb) on my site.
I am going to use encoding UTF-8 for viewing, but how to change the input(the content) to UTF-8? Can anybody teach me how to solve....
thank you so much

thanks^_

but i try this:
function utf8_encode_array (&$array, $key) {
if(is_array($array)) {
array_walk ($array, 'utf8_encode_array');
} else {
$array = utf8_encode($array);
}
}

The content is encoded but when I choose UTF8 encoding to view in browser, it didn't show me the correct content >_<
