Problem with encoding mail

[Alice_]

I use Nuxeo DM 5.5 and I found a problem in Mail Folder: in the mail text, there is a wrong encoding and some character (i.e: à, è, ì ...) are wrongly displayed. I checked my database (postgreSQL with UTF-8 encoding) and the wrong characters are present there too.

I have the same encoding problem with sending an notification by a mail template.
