Gmail subject mangled from encoding

When sending an email via Gmail, the Subject is directly filled by a variable which contains characters like “ã” or “ç”. I need to encode the Subject to iso-8859-1 as per the RFC standard.

This will show as this:

I have same problem. Even when I write same content directly, without using Expression.

Update: If I use “textAsHtml” instead of “html”, subject stays okay…

Can you please explain to me where you see the TextAsHTML? I put it as a text, and the problem persists. It’s so frustrating.

Sorry Hugo, I am unable to find what attribute I meant by that. Only thing I know is I was able to make ti happen, but another problem comes out.

TL;DR: I moved from gmail and used MailerSend, as I was unable to make it work. AFAIK problem with the encoding persists.
