Problem with unsupported font

[eluser]npCoda[/eluser]
My project is in English. When some names such as 'Daniël' appears in the page it comes like Dani�l. Actually this the Dutch word.

So how can I solve it??
Thank you for your suggestion.

I use:

Code:

$html = htmlspecialchars($utf8_string, ENT_COMPAT, 'UTF-8');

It works.
