I'm a writer and I belong to a critique group. We send each other sections of our writing to look over and offer suggestions on. Most of us write in MS Word and when we copy and paste into an email it looks fine to us but when we send it it comes out with weird symbols in place of things like quotation marks (lots of these in dialogue), commas, apostrophes and other punctuation.

I just found this on the web that explains it and gives a suggestion on how to fix it, which I have yet to try:
Avoid Weird Formatting When Copying & Pasting Text

The other day I was watching the CNN ticker at the bottom of the screen and the sentence looked like this:

"Britney?s children get to see their mom."

Did you ever see this? This ever happen to you? It happens to me in our email marketing campaigns in two ways: When I copy text off of the blog (HTML page) to paste into my Email Canvas in VR, OR when I write the blog first in Microsoft Word, then copy and paste directly into the blog.
What's happening is that Microsoft Word inserts strange characters that replace quotes, dashes and apostrophes like the one example above. Also, if you're copying and pasting right from a web page you may be taking some HTML code you don't necessarily see.
What can you do?
1. If You Use Word - Then copy your item from Word. Go to the area you want to paste the copy into in your Email Canvas and highlight it. Then click on the "paste from Word" symbol in the toolbar that looks like this: and a screen with a large text field will appear. Paste your text into the screen and click Insert. You may have to choose a font and a size but you won't get any weird characters or formatting.
2. If You Don't Use Word - Paste your text into Notepad if you're on a PC or in TextEdit if you're on a Mac. Then copy and paste your copy into your web document.
Hope this helps, it sure helped me!
