NEED HELP!!! When i tried to send my friend a book i wrote, i sent her the first 21 pages, it worked until i got to the 22. then it suddenly said, "Invalid text encoding for message body" Can anyone help me?

I feel really creative right now, so I think i will go sketch something up. :)

I just found Ellen schreiber's journal! Im so excited! I Have also found a way to flow the details into my book without any awkwardness. Its going great!
