Subject: 31.0.50; Error sending mail using SMTP - base64 encoding fails

When I try to send mail with emacs using SMTP, I get error "Multibyte character
in data for base64 encoding".

In the current code I have narrowed it down to line 637 in smtpmail.el, where an
attempt is made to base64 encode a string containing the password which, of
course, can contain multibyte characters.

With a simple password some time ago, I could send mail.
