Description:
------------
When i use mysql_real_escape_string() with mysql_set_charset() forcing to use 'latin1' the accented characters dissapear from the insert string. 

SHOW VARIABLES LIKE 'character_set%';
------------------------------------
character_set_client	  latin1
character_set_connection  latin1
character_set_database	  latin1
character_set_filesystem  binary
character_set_results	  latin1
character_set_server	  latin1
character_set_system	  utf8

PHP info

PHP API 	20041225
PHP Extension 	20060613
Zend Extension 	220060519 

I realize that if i comment the mysql_set_charset() command i have no problems. anyway, if i try to get the connection character (with or without this command) i'll always get 'latin1', but i just think that this commando shouldn't cause problems.. till today i have it trying to stabilize my framework environment

Test script:
---------------
# From the very beginning i disable the magic quotes if it's set
ini_set('magic_quotes_gpc', 0);

# I create a connection like this
$link = mysql_connect(SQL_HOST, SQL_USER, SQL_PASS);
mysql_select_db(SQL_INSTANCE, $link);

# Use the "forced" character set for the connection
mysql_set_charset('latin1', $link);

# In my code i have a class that performs all validation according to the type of content i'm specting... in this case string's validation
Class vaccine
{
  public static function forString($value)
  {
    if($value == null || $value == 'null')
      return 'NULL';
    
    return strlen($value)
         ? '\''. mysql_real_escape_string($value) .'\''
         : 'NULL';
  }
}

# then if i'm going to insert in db
$query = "INSERT INTO TABLE VALUES(". Vaccine::forString('this text has accents from here áéíóú') .")"

Do you get this also with 5.3?
