Still encoding problems when sending email

[jerome]

When sending email messages to the end user or administrator, sometimes a character encoding error remains as can be shown in the traceback below :

Unfortunately the context of this traceback was lost, since it was detected only 12 days after it happened (my fault, it happened on my own machine...)

(In [3464]) Added proper encoding to fix #35.
