I noticed that when sending email notifications, SendGrid converts some HTML entries (such as copyright, trademark, registered trademark) to the Unicode characters. So, it would replace © in the HTML message body with the © character. This may cause unintended consequences (I do not think it does this anymore, but not long ago Gmail would clip messages with the © character). There is no reason for SendGrid to make this conversion, unless there is a flag in the API to indicate that this is the desired behavior, and I did not see one. Can this behavior be stopped?
