💣 Time to add special characters to your email subjects
I came across this problem when someone asked for emails from my web application to stand out in their inbox. The emails were informing a user that an alarm had gone off and they would like a bomb or similar to appear in their inbox.
After a bit of googling and finding many sites that explained how to do this manually (cut and paste characters or using particular 'clipboard' style tools). I figured out the answer of how to embed the unicode into the message.
So given my script (a nodejs application) I followed the recipe below:
Find the character the user is interested in for example search a site like http://www.fileformat.info
Once you have found the required character locate the UTF-8 (hex string) in the case of the alarm clock (http://www.fileformat.info/info/unicode/char/23f0/index.htm): 'e28fb0'
Embed this in the subject string via: =?UTF-8?Q?=E2=8F=B0?= (ie enclose the hex in =?UTF-8?Q?= and ?=).
Send message and as long as their mail agent supports the character hey hoe!
