functions_email.php Charset CHARSET : "iso-8859-1" or UFT-8

I believe that zen-cart is basically using UTF-8. I just came across the:

includes/functions/functions_email.php

that has the charset as:

CHARSET : "iso-8859-1";

Should it be changed to UTF-8?

Thanks!

You are misquoting the code.

The full line is this: ```
$mail->CharSet = (defined('CHARSET')) ? CHARSET : "iso-8859-1";

And, if you read it correctly it uses iso-8859-1 only IF the constant for 'CHARSET' is not defined.  And, since any properly installed Zen Cart WILL already have CHARSET defined, that means iso-8859-1 would never be used. That code is only a fallback for VERY RARE situations when CHARSET isn't defined. 
And, if CHARSET is not defined, then there will be numerous far more serious issues.

So, in summary: ignore it.

Thank you!
