SOGo and international characters problem

Hello,

I’m testing nethserver 7 final as web mail, Sogo looks very nice and when displaying messages with international characters in (content-type: text/plain; charset=utf-8) format everything is fine but I found that when it displays a message with international characters set to (Content-Type: text/plain; charset=“windows-1253” Content-Transfer-Encoding: base64) then the characters are not displayed correctly and the mail is unreadable.

Roundcube and outlook does not have the same problem, everything looks fine over there.
I tried adding the character set in httpd.conf and php.ini with no success, it must be something else.

Thanks for your time!

can you send me the email please to stephdl at de-labrusse.fr
