I made some additional tests and found a workaround for the problem:
turned 'off' function overload for mail(). This works since no character
encoding translation is involved.
I found where the additional quotes are coming from - the mime header of
the message to send is:
Content-Type: text/plain; charset="UTF-8"
When changed the code to send:
Content-Type: text/plain; charset=UTF-8
the error disappeared along with the message body :) Obviously the
encoding is derived from this header.
I will continue to investigate the problem, but it would be better if
somebody from the code authors take care of this problem.

Anastas
