php - Unicode characters become question marks after inserting into the database

Question

When I insert some text written in Unicode into database, they become question marks. Database encoding is set to UTF-8. What else may be incorrect? When I check in phpMyAdmin there are question marks inserted only!

This is the code I use for connecting to database:

define ("DB_HOST", "localhost"); // Set database host
define ("DB_USER", "root"); // Set database user
define ("DB_PASS","password"); // Set database password
define ("DB_NAME","name"); // Set database name

$link = mysql_connect(DB_HOST, DB_USER, DB_PASS) or die("Couldn't make connection.");
$db = mysql_select_db(DB_NAME, $link) or die("Couldn't select database");

mysql_set_charset('utf8',$link);
mysql_query("SET CHARACTER SET utf8");

Answer 1

Is the text you inserted encoded in UTF-8 too? Or is your PHP files not UTF-8? Have you set the MySQL Client connection to UTF-8?

If not, then that is probably the cause of the problem.
