Gibberish in Greek email subject line

Hi there,

Congrats for your excellent plugin. I have found a bug. If the post title is in Greek (e.g. “Το πε?ραμα του Jamie Oliver” = Jamie Oliver’s experiment), then when you press the email button you get gibberish as the email subject (e.g. “?¤?? ???μ?ˉ???±???± ?????? Jamie Oliver”):

Thanks,
