    You should have the same encoding everywhere and define it.

    Define the charset like this;

    <meta charset="UTF-8" />

    and in the header;

    header('Content-Type: text/html; charset=utf-8');

    You can also write your characters with html characters, however it is always good to define the charset.

    If you have ISO-8859-1(latin1) data in your database, and the rest of the site in UTF-8. Then define the charset-tag as above and use the function utf8_encode() to give the string a properly encoding. There is also a reverse function called utf8_decode()
