mysql DB insert failing the utf8 characters

mysql DB insert failing the utf8 characters

This is something not new, not even in this forums but I couldn't find
something similar.
Look, I am trying to insert this char ü , into my mysql DB, in the db at
the end the char appears like " ü ".
This is my configuration:
Format Compact
Collation utf8_general_ci
Next autoindex 22
Creation Aug 14, 2013 at 09:26 PM
My php insert looks like this:
#mysql_set_charset('utf8');
#mysql_query("set names 'utf8'");
if (!mysqli_query($conexion,$sql_insert))
{
die('Error: ' . mysqli_error($conexion));
}
echo "1 record added";
I already commented out the charset statement and the set names.
Not sure what else to try, any suggestion?
