I sent an email the other day, but now I notice the characters '<?xml' are appearing at the end of the last line of my email. I didn't type those characters when I was composing the email, yet they're showing as if I did.
I decided to load the email into a text editor (TextWrangler) and selected the option to display XML, but as far as I can see all lines of XML are properly contained within the '<>' characters and therefore should be interpreted as XML code.
The line of XML containing the offending characters immediately follows the text body of my email and appears in the text editor as:
<?xml version="1.0" encoding="UTF-8"?>
As can be seen the XML code is properly enclosed, yet it appears Mail, for some reason, is seeing the line as if it were:
<?xml<?xml version="1.0" encoding="UTF-8"?>
Thus interpreting the first five characters as part of the text body of the email. I tried to be clever by removing the '<?xml' characters from the line and even retyping the line, but when I save and rebuild the Sent mailbox the '<?xml' characters still persist in appearing at the end of my email.
Can anyone expert on XML and Mail help me out?
