Remove " from text to be sent to Postmark and breaks JSON

[alessandro]

In my app I have a multiline text input and my users often use " as special characters.

I send the text via postmark in transactional mails and the " special characters always cause an error as postmark thinks the special characters are JSON code.

How can I format the input when running the workflow so it removes the " from the text?

Thank you
