Emoji in email subject line

Question

Recently I have received newsletters with emojis in the subject line..

I have copy/pasted a subject from the source of a newsletter

Subject: =?utf-8?Q?=F0=9F=94=A5=C2=A06=20days=20left=20until=20we=20meet=20you=20at=20TechBBQ=C2=A0=F0=9F=94=A5?=

I use phpmailer to send emails.. How is it possible to reuse the same icons when sending messages?

Answer 1

$subject = "\xF0\x9F\x94\xA5 test \xF0\x9F\x94\xA5";

This will put a fire emoji like the above in the beginning and the end of the string when sending with phpmailer. Rememeber to set the encoding in the mail to UTF-8
