I'm having an issue with the email body formatting on my 10.0.2 site. When I enter a custom message for my User Account Created email notification, all the spaces are replaced with non-breaking spaces ( ) in the source code causing the email to stretch out extremely wide. If I find/replace the non-breaking spaces with regular spaces and paste the message back into the editor and save, I can see that the page re-formats my message, and if I look in the source code again the non-breaking spaces are back. Even if I manually replace all the nbsp's with regular spaces inside the message editor, when I click save they get reformatted into nbsp's again.
Please help!
