I use phpmyadmin and mysql. Here is my table:
But when i enter some characters like Ö,Ç,İ,Ğ,Ü,Ş to the textboxes and update the database, i get weird characters such as Ã?Ä?İıÅ?Å?Ã?çÃ?ö. How can i fix this? I tried utf8_bin and utf8turkish_ci as collation but it does not work. Can anyone help?
Thanks
Edit: Here is where i edit my database with new user inputs:
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
package classes;
import java.io.Serializable;
import java.sql.Connection;
import java.sql.PreparedStatement;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import javax.faces.context.FacesContext;
/**
*
* @author SUUSER
*/
@ManagedBean(name = "user")
@SessionScoped
public class User implements Serializable {
public static Customer customer;
private Connection con=null;
public void setCustomer(Customer customer) {
User.customer = customer;
}
public Customer getCustomer() {
return customer;
}
public User() {
}
public void editInfo() {
String name = customer.getName(), surname = customer.getSurname(), password = customer.getPassword();
String phone = customer.getPhone(), address = customer.getAddress(), email = customer.getEmail();
try {
con=DBConnect.connect();
int result = -1;
PreparedStatement checkDB = (PreparedStatement) con.prepareStatement(
"UPDATE users set password=?,name=?,surname=?,phone=?,address=?,"
+ "email=? where username=?");
checkDB.setString(7, customer.getUsername());
checkDB.setString(1, password);
checkDB.setString(2, name);
checkDB.setString(3, surname);
checkDB.setString(4, phone);
checkDB.setString(5, address);
checkDB.setString(6, email);
result = checkDB.executeUpdate();
con.close();
FacesContext.getCurrentInstance().getExternalContext().redirect("editsuccesfull.xhtml");
} catch (Exception e) {
e.printStackTrace();
}
}
}

I actually had a similar problem while allowing UTF-8 character sets to be used for usernames.
first step, in your form code add:
accept-charset="utf-8"
into the accept=charset form attribute
Second step is to add a php header
header("Content-type: text/html; charset=utf-8");
now, In your processing php file you need to add the header again
header("Content-type: text/html; charset=utf-8");
now before choosing the database information use
mysql_set_charset('utf8');
Should work from there.. This is UTF8, So if you want to change it to a lower set of characters like turkish, enter the turkish encoding..
EDIT: This is in PHP, HTML. So hopefully it guides you in the right direction for ASP.NET.

You should try Base64 for characters conversion. It is really effective. I had a problem about writing characters to file, some symbols disappeared or changed. When i used to Base64 converter,I solved this problem. Check Base64
Example code for convertion;
public String encode64(String resultText) {
String encodeText= Base64.encodeBytes(resultText.getBytes()); //convert base64
return encodeText;
}
public byte[] decode64(String text) {
byte[] decodeText= Base64.decode(text); //deconvert base64
return decodeText;
}
