I'm having an issue with special characters in email subject and attachment filenames. I've tried lots of different versions/builds (2017 and up).
I'm using the standard 'Send' action on the Post Sales Invoice card using Email: Yes (Prompt for Settings)
If I put 'æ' in the subject and send using SMTP (un-tick the 'Edit in Outlook') it will show up as 'Ã¦' in the email.
If I put 'æ' in the subject and edit the email in Outlook before sending it, it will work correctly.
I know it's an encoding problem because when it fails the 'æ' has been encoded as =C3=A6 but when it works it has been encoded as =E6 but I have no idea what I can do to fix this.
Interestingly if I put in lots of special characters the entire string is Base64 encoded and everything works fine!
