Hmm, a quick google for wingdings and webdings shows a lot of people having trouble with these fonts, and almost as many people somewhat naïvely advising their use, without understanding that these character sets are not web-safe. Here's an explanation of why you shouldn't use them: http://www.alanwood.net/demos/wingdings.html The discussion there talks about web pages, but when you use HTML to format a document it's somewhat moot as to whether it's a web page or an email message. I use unicode and abcTajpu for such things. https://addons.mozilla.org/en-us/thunderbird/addon/abctajpu/ Do you not get messages from Outlook users peppered with stray characters, where they've tried to insert an icon for a phone? The "J" in the following was probably intended to be a smiley.
