To try and replicate the issue away from the full production scripts, I've written a test with the sending code copied directly from the production code. A few variables have changed names and a couple of other tweaks to make it run but the sending code is as faithful to production as I can get it. The sending mechanism is extremely similar, so it's unlikely to be that. The sending method is toggled in the code below by setting $METHOD true or false.

Method true stores the message in a database table. The data types and DB engine are the same as the production DB. There's a bit of substitution and then it's sent.

Method false bypasses storing and retrieving from the database. It does a similar substitution and sends.

Running the script in a web environment sends email, in both cases, without the emojis being properly reproduced. So, I set up CRON to run the script...again, both methods produce emails with corrupted emojis.

It appears that it's not the DB that's affecting it, and it's not the CRON vs web environment that's affecting it...

I'm finding this really tricky to debug as I cannot think of a way of inspecting what is happening between the data being passed to MIME::Lite and it appearing in my email client.

#!/usr/bin/perl

use CGI::Carp qw(fatalsToBrowser);
