Sending email by PHP does not show accents correctly

Question

Situation

I have an email newsletter system, on it is sent emails to customers every day, but I realized that when using accents like ´~'^, the words disfigure getting like this: ÓAÃÃÃ forward.

Well, I’ve tried to include <meta charset="UTF-8"> and other encodings but nothing changes but saving with UTF-8 encoding.

The subject also has the same problem, IE, the entire email, since subject to message come out with disfigured accents.

The code php is like this:

<?php              
$msg_para    = $_POST["msg_para"];
$msg_assunto = $_POST["msg_assunto"];
$msg_tipo    = $_POST["msg_tipo"];
$mensagem    = $_POST["mensagem"];
if($msg_para == "todos"){
$sql = mysql_query("SELECT * FROM list-emails WHERE ativo = 'online'");
$total = mysql_num_rows($sql);
$mailok = 0;
$falha  = 0;
while($lista = mysql_fetch_array($sql)){
$email = $lista["email"];
$cabecalho  = "From: $a_nome <$a_email>";
$cabecalho .= "\nReply-To: $a_nome <$a_email>";
$cabecalho .= "\nContent-Type: $msg_tipo";
if(@mail($email,$msg_assunto,$mensagem,$cabecalho)){
$mailok = $mailok + 1;
$msg = "<font color=green>SUCESSO!</font>";
}
else{
$falha = $falha + 1;
$msg = "<font color=red>FALHA!</font>";
}
?>
<font face="Arial" size="2">Enviando para <b><?=$email?></b>...
<b><?=$msg?></b></font><br>
<?php } ?>
<script>alert("<?=$total?> e-mails deveriam ser enviados...\n<?=$mailok?> 
foram mandados corretamente,\n<?=$falha?> falharam!\n") </script>
<?php
}
else{
$cabecalho  = "From: $a_nome <$a_email>";
$cabecalho .= "\nReply-To: $a_nome <$a_email>";
$cabecalho .= "\nContent-Type: $msg_tipo";
if(@mail($msg_para,$msg_assunto,$mensagem,$cabecalho)){
$msg = "<font color=green>SUCESSO!</font>";
}
else{
$msg = "<font color=red>FALHA!</font>";
}
?>
<font face="Arial" size="2">Enviando para <b><?=$msg_para?></b>...
<b><?=$msg?></b></font><br><?php
}
}
else{
echo "<script>location.href='login.php'</script>";
}
?>

Briefly I need some way to put encoding UTF-8 or any other that does not have problems with accents in the email.

One thing I realized is that the name of the email set in config.php comes out with normal accents, the only fields that have this problem are the subject matter and that of message. The code of config.php is like this:

<?php
$host    = "4322-8922";
$usuario = "5";
$senha   = "4";
$banco   = "321";
mysql_connect($host,$usuario,$senha);
mysql_select_db($banco);
$a_nome          = "Téstê dê Ácëñtõs StáckÔvèrFlôw";
$a_email         = "[email protected]"; 
$formato_msg     = "Text/HTML"; 
$confirm_assunto = "Confirmação de Email $a_nome"; //esse assunto é especificamente para a parte de newsletter
$titulo          = "Máîs Úm Tèstê"; 
$url             = "http://answall.com";
$url_sist        = "http://answall.com";
?>

And the result of the e-mail is like this:

Using text converters is out of the question since sending email email is done directly by the system, this would cause a slowdown in the process.

Answer 1

You need to configure the PHP header.

Put this at the top of the page:

header('Content-type: text/html; charset=utf-8');

If it works give a UP here.

Answer 2

How do you have these lines:

$msg_tipo    = $_POST["msg_tipo"];
$cabecalho .= "\nContent-Type: $msg_tipo";

is a matter of ensuring that the variable $msg_tipo has the correct charset, either coming from the POST, or putting in the sending code.

The correct format is this:

              Content-Type: text/html; charset="UTF-8"
aqui você adapta pro seu caso  ---^      ^---- fundamental além do tipo certo, o charset

Note that text/html was just an example, need to set according to the content. The important thing is to add the ; charset="UTF-8" at the end.

(not to be confused with the Content-Type HTTP header, we’re talking about the email/MIME header type)

In addition, it is important that the page where the form is also using the correct charset. ISO-8859-1 and UTF-8 are the most common and suitable for shipping.

Here are some more considerations (in English):

Answer 3

The problem was solved simply adding utf8_decode() in the variables $_POST, that is, had no connection with the Content-Type or message body and not with file encoding.

Currently with the solution of the problem, the code is like this:

<?php              
$msg_para    = $_POST["msg_para"];
$msg_assunto = utf8_decode($_POST["msg_assunto"]);
$msg_tipo    = $_POST["msg_tipo"];
$mensagem    = utf8_decode($_POST["mensagem"]);
if($msg_para == "todos"){
$sql = mysql_query("SELECT * FROM n_emails WHERE ativo = 's'");
$total = mysql_num_rows($sql);
$mailok = 0;
$falha  = 0;
while($lista = mysql_fetch_array($sql)){
$email = $lista["email"];
$cabecalho  = "From: $a_nome <$a_email>";
$cabecalho .= "\nReply-To: $a_nome <$a_email>";
$cabecalho .= "\nContent-Type: $msg_tipo";
 if(@mail($email,$msg_assunto,$mensagem,$cabecalho)){
 $mailok = $mailok + 1;
 $msg = "<font color=green>SUCESSO!</font>";
 }
 else{
 $falha = $falha + 1;
 $msg = "<font color=red>FALHA!</font>";
 }
 ?>
 <font face="Arial" size="2">Enviando para <b><?=$email?></b>...
 <b><?=$msg?></b></font><br>
 <?php } ?>
 <script>alert("<?=$total?> e-mails deveriam ser enviados...\n<?=$mailok?> foram mandados corretamente,\n<?=$falha?> falharam!\n")</script>
 <?php

I thank those who tried to help and hope to help other people who are in trouble too.

Answer 4

I make use of Phpmailer and my emails are sent with the correct encoding, for this I added in my email script, in the first line I added the code below:

<meta http-equiv="content-type" content="text/html; charset=UTF-8">
