UTF-8

After this modification i have - any date in datebase in any languages.
A have in datebase - Rusian, English , Latvia - (Аги.(Āģī)) in one string.

Need Export all tables from mysql and  chnage this dump file to UTF-8.
Change in dump file where;  DEFAULT CHARSET=*** COLLATE=**** >-TO-> DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci ;

Make new database with - DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci ;

And import file with you date.

Than install Eny UTF-8 language in FA, Make this dafault. Take language file *.po *.mo from english - convert this files to files with UTF-8 encoding. And put files in you any UTF-8 language in FA.

Notepad++ work great for convert between encodind.

Than change down.

* ..\frontaccount\includes\db\connect_db.inc

function db_query($sql, $err_msg=null)

Add like this

//My change: for UTF-8
  mysql_query("SET NAMES 'utf8';");
  mysql_query("SET CHARACTER SET 'utf8';");
  mysql_query("SET SESSION collation_connection = 'utf8_general_ci';");
//My change: for UTF-8

May be also need config mysql

MySQL server my.cnf or Windows my.ini:   

[client] 

default-character-set= utf8   

[mysql]
collation_server = utf8_unicode_ci

character_set_server = utf8

default-character-set=utf8

init-connect='SET collation_connection = utf8_general_ci'

init-connect='SET NAMES utf8'

[mysqld]

default-character-set=utf8
