I have been trying to send an HTML email with PHPMailer containing emojis:
$mail = new PHPMailer();
$mail->isHTML(true);
$mail->CharSet = "UTF-8";
$mail->Subject = "😀 😃 😄 😁 😆 😅 😂 🤣 😊 😇 🙂 🙃 😉 😌";
$mail->Body = "😀 😃 😄 😁 😆 😅 😂 🤣 😊 😇 🙂 🙃 😉 😌";
However, the emojis are only displayed correctly in the subject; in the body, they are replaced by question marks (in Thunderbird and Outlook). The email does contain HTML, so just setting isHTML to false will not suffice. I have looked at Send unicode emoji with PHPMailer , but it does not seem to work for me, as the character set is already set to UTF-8. The content is user-generated (the user uses their own mobile keyboard to insert the emoji), so manually replacing every emoji with, for example, an image is not an option. Preferably the solution would be dynamic, so that new emojis also work whenever they come out.
you need to specify emoji's unicode value and try below method.
echo json_decode('"\uD83D\uDE00"');
Also you can use UTF-8 notation from this this table:
example:
😁 \xF0\x9F\x98\x81 GRINNING FACE WITH SMILING EYES
I use the PHPMailer as my mail tool for a project. I should send to a user a letter which contains Romanian alphabet (the main difference from English letters is the fact of issue such letters as â, ă, î, ș, ț).
I set charset UTF-8 for my letter:
$mail->CharSet = 'UTF-8';
but it didn't help me. I see in Google mail signs ? instead â, ă, î, ș or ț.
How can I fix it?
Aparently, encoding japanese emails is somewhat challenging, which I am slowly discovering myself. In case there are any experts (even those with limited experience will do), can I please have some guidelines as to how to do it, how to test it and how to verify it?
Bear in mind that I've never set foot anywhere near Japan, it is simply that the product I'm developing is used there, among other places.
What (I think) I know so far is following:
- Japanese emails should be encoded in ISO-2022-JP, Japanese JIS codepage 50220 or possibly SHIFT_JIS codepage 932
- Email transfer encoding should be set to Base64 for plain text and 7Bit for Html
- Email subject should be encoded separately to start with "=?ISO-2022-JP?B?" (don't know what this is supposed to mean). I've tried encoding the subject with
"=?ISO-2022-JP?B?" + Convert.ToBase64String(Encoding.Unicode.GetBytes(subject))
which basically gives the encoded string as expected but it doesn't get presented as any japanese text in an email program
- I've tested in Outlook 2003, Outlook Express and GMail
Any help would be greatly appreciated
Ok, so to post a short update, thanks to the two helpful answers, I've managed to get the right format and encoding. Now, Outlook gives something that resembles the correct subject:
=?iso-2022-jp?B?6 Japanese test に各々の視点で語ってもらった。 6相当の防水?=
However, the exact same email in Outlook Express gives subject like this:
=?iso-2022-jp?B?6 Japanese test 縺ｫ蜷・・・隕也せ縺ｧ隱槭▲縺ｦ繧ゅｉ縺｣縺溘・ 6逶ｸ蠖薙・髦ｲ豌ｴ?=
Furthermore, when viewed in the Inbox view in Outlook Express, the email subject is even more weird, like this:
=?iso-2022-jp?B?6 Japanese test ??????????????? 6???????=
Gmail seems to be working in the similar fashion to Outlook, which looks correct.
I just can't get my head around this one.
I've been dealing with Japanese encodings for almost 20 years and so I can sympathize with your difficulties. Websites that I've worked on send hundreds of emails daily to Japanese customers so I can share with you what's worked for us.
First of all, do not use Shift-JIS. I personally receive tons of Japanese emails and almost never are they encoded using Shift-JIS. I think an old (circa Win 98?) version of Outlook Express encoded outgoing mail using Shift-JIS, but nowadays you just don't see it.
As you've figured out, you need to use ISO-2022-JP as your encoding for at least anything that goes in the mail header. This includes the Subject, To line, and CC line. UTF-8 will also work in most cases, but it will not work on Yahoo Japan mail, and as you can imagine, many Japanese users use Yahoo Japan mail.
You can use UTF-8 in the body of the email, but it is recommended that you base64 encode the UTF-8 encoded Japanese text and put that in the body instead of raw UTF-8 text. However, in practice, I believe that raw UTF-8 text will work fine these days, for the body of the email.
As I alluded to above, you need to at least test on Outlook (Exchange), Outlook Express (IMAP/POP3), and Yahoo Japan web mail. Yahoo Japan is the trickiest because I believe they use EUC for the encoding of their web pages, and so you need to follow the correct standards for your emails or they won't work (ISO-2022-JP is the standard for sending Japanese emails).
Also, your subject line should not exceed 75 characters per line. That is, 75 characters after you've encoded in ISO-2022-JP and base64, not 75 characters before conversion. If you exceed 75 characters, you need to break your encoded subject into multiple lines, starting with "=?iso-2022-jp?B?" and ending with "?=" on each line. If you don't do this, your subject might get truncated (depending on the email reader, and also the content of your subject text). According to RFC 2047:
"An 'encoded-word' may not be more than 75 characters long, including 'charset', 'encoding', 'encoded-text', and delimiters. If it is desirable to encode more text than will fit in an 'encoded-word' of 75 characters, multiple 'encoded-word's (separated by CRLF SPACE) may be used."
Here's some sample PHP code to encode the subject:
// Convert Japanese subject to ISO-2022-JP (JIS is essentially ISO-2022-JP)
$subject = mb_convert_encoding ($subject, "JIS", "SJIS");
// Now, base64 encode the subject
$subject = base64_encode ($subject);
// Add the encoding markers to the subject
$subject = "=?iso-2022-jp?B?" . $subject . "?=";
// Now, $subject can be placed as-is into the raw mail header.
See RFC 2047 for a complete description of how to encode your email header.
Check http://en.wikipedia.org/wiki/MIME#Encoded-Word for a description on how to encode header fields in MIME-compliant messages. You seem to be missing a “?=” at the end of your subject.
=?ISO-2022-JP?B?TEXTTEXT...
ISO_2022-JP means that string is encoded in ISO-2022-JP codepage (eg. not Unicode)
B means that string is bese64 encoded
In your example, you should just supply your string in ISO-2022-JP instead of Unicode.
I have some experience composing and sending email in japanese...Normally you have to beware what encoding used for operating system and how you store your japanese strings!
My Mail objects are normally encoded as follows:
string s = "V‚µ‚¢ŠwK–#‚Ì‚²’ñˆÄ"; // Our japanese are shift-jis encoded, so it appears like garbled
MailMessage message = new MailMessage();
message.BodyEncoding = Encoding.GetEncoding("iso-2022-jp");
message.SubjectEncoding = Encoding.GetEncoding("iso-2022-jp");
message.Subject = s.ToEncoding(Encoding.GetEncoding("Shift-Jis")); // Change the encoding to whatever your source is
message.Body = s.ToEncoding(Encoding.GetEncoding("Shift-Jis")); // Change the encoding to whatever your source is
Then i have an extension method to which does the conversion for me:
public static string ToEncoding(this string s, Encoding targetEncoding)
{
return s == null ? null : targetEncoding.GetString(Encoding.GetEncoding(1252).GetBytes(s)); //1252 is the windows OS codepage
}
something like this should get the job done in python:
#!/usr/bin/python
# -*- mode: python; coding: utf-8 -*-

First of all you should be using:
Encoding.GetEncoding("ISO-2022-JP")
to convert your subject line into bytes that will be processed by Convert.ToBase64String().
=?ISO-2022-JP?B?TEXTTEXT...?= tells the receiving mail client which encoding was used on the sender's side to convert japanese "letters" into a byte stream.
Currently you're using UTF-16 to encode, but specifying ISO-2022-JP to decode. These are obviously two different encodings, I guess, just like ISO-8859-1 is different from Unicode (most extended western-europe chars are represented by one byte in ISO-XXX, but two bytes in Unicode).
I'm not sure what you mean about UTF-8 being second-class citizen. As long as the receiving mail client understands UTF-8 and is able to convert it to the current japanese locale, everything is fine.
<?php
function sendMail($to, $subject, $body, $from_email,$from_name)
{
$headers = "MIME-Version: 1.0 \n" ;
$headers .= "From: " .
"".mb_encode_mimeheader (mb_convert_encoding($from_name,"ISO-2022-JP","AUTO")) ."" .
"<".$from_email."> \n";
$headers .= "Reply-To: " .
"".mb_encode_mimeheader (mb_convert_encoding($from_name,"ISO-2022-JP","AUTO")) ."" .
"<".$from_email."> \n";
$headers .= "Content-Type: text/plain;charset=ISO-2022-JP \n";
/* Convert body to same encoding as stated
in Content-Type header above */
$body = mb_convert_encoding($body, "ISO-2022-JP","AUTO");
/* Mail, optional parameters. */
$sendmail_params = "-f$from_email";
mb_language("ja");
$subject = mb_convert_encoding($subject, "ISO-2022-JP","AUTO");
$subject = mb_encode_mimeheader($subject);
$result = mail($to, $subject, $body, $headers, $sendmail_params);
return $result;
}
Introduction of Japanese encoding to e-mail happened at JUNET(UUCP based nation-wide network) in early 90's.
At that time, RFC1468 was defined.
If you follow RFC1468 in plain text mail, there would be no problem.
If you want to handle html mail, RFC1468 is useless except for header parts.
Here's what I use to send Japanese emails. Subject line looks fine in Outlook 2010, gmail and on iPhone.
Encoding encoding = Encoding.GetEncoding("iso-2022-jp");
byte[] bytes = encoding.GetBytes(subject);
string uuEncoded = Convert.ToBase64String(bytes);
subject = "=?iso-2022-jp?B?" + uuEncoded + "?=";
// not sure this is actually necessary...
mailMessage.SubjectEncoding = Encoding.GetEncoding("iso-2022-jp");
I think im doing things correct:
Im specifying charset of PHPMailer object: $mail->CharSet = "UTF-8";
Charsets of mail body and php script are UTF-8 too
But email arrives with this kind of errors (words are broken by black quarter with "?" symbol:
опреÐ �елени
оÑ �ибка определения
click to see the screenshot of example email
Update 1
Found something kinda chinese glyphs (but not cyrillyc symbols) in the email's source
Try:
$mail = new PHPMailer();
$mail->CharSet = 'UTF-8';
as staded by user2354947 in PHPMailer character encoding issues
the CharSet definition must be entered after the PHPMailer()
similar to my problem PHP ASCII to UTF-8 does not work
i found out that when you pull your data from sql, you need to transform it to UTF-8
When I send an email containing £ using PHP mail it appears in outlook/hotmail as £. In Gmail/thunderbird it's fine.
Any idea how I can fix this?
The problem is, the client doesn't know what encoding is used to encode the subject. Whatever your application sets in Content-Type header only applies to the body of the email, not the headers.
Usually this affects the following headers:
Subject
From
To
In order to use different encodings your internationalized header lines should be MIME-encoded (as of RFC 2047), using one of the two methods: base64 (B) or modified quoted-printable (Q). The encoded subject usually looks like this:
Subject: =?ISO-8859-1?Q?Pr=FCfung_f=FCr?= Entwerfen von einer MIME kopfzeile
This may look difficult, but there is one very handy helper function in PHP which does all the magic:
iconv_mime_encode() - Composes a MIME header field
Alternatively you may look into discussion under:
quoted_printable_encode() - Convert a 8 bit string to a quoted-printable string
Before using quoted_printable_encode() directly you neet to take into account that long lines need to be split at certain length and spaces need to be replaced with underscore "_".
Just today I fixed a similar subject encoding issue by using phpmailer instead of php's builtin mail:
$mail = new PHPMailer(true);
$mail->IsSMTP();
$mail->CharSet = "utf8";
$mail->Subject = $mail->EncodeHeader("You won £10000000!");
....
$retval = $mail->Send();
Usually I use the mb_convert_encoding() function
mb_convert_encoding($string, "UTF-8"); //AUTO DETECT AND CONVERT
mb_convert_encoding($string, "UTF-8", "latin1"); //MANUAL SET - CHANGE latin1 TO CURRENT ENCODING
Try to use UTF-8 encoding in your email.
this had results for my
<?php $subject = "=?UTF-8?B?" . base64_encode($subject) . "?="; ?>
