Answer 1

If the problem is not in the files to display in the frame, may be the problem in the data. I always try to configure PHP, Apache and MySQL with UTF8. For this, I edit some configuration files.

MySQL: /etc/my.cnf

[client]
default-character-set=utf8

[mysqld]
character-set-server=utf8
init-connect='SET NAMES utf8'
character-set-client=utf8
character_set_results=utf8

Then:

sudo service mysql restart

PHP: /etc/php.ini

default_charset = "UTF-8"

Apache: /etc/apache2/conf.d/charset

AddDefaultCharset UTF-8

Then:

sudo service apache2 restart

Another thing to consider when connecting to the database:

...
$link = mysql_connect(SERVER, USER, PASSWORD);
mysql_set_charset('utf8', $link);
...

You can see all characters related variables using:

SHOW VARIABLES LIKE 'c%';

You must make sure that the page displayed in the iframe tag has also:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>

I hope it helps somewhat.
