Hi Stephan,

Not really, the Email Connector in Diafaan SMS Server supports the UTF-8 character set and can forward Unicode email to SMS. Diafaan SMS Server has no problem with Chinese or Arabic email.

The problem seems to be that your hardware device sets the Content-Transfer-Encoding value to UTF-8 and this is an illegal value for the Content-Transfer-Encoding field in email messages. Unfortunately the email library that Diafaan SMS Server uses is very strict and does not allow invalid encodings. Other mail clients are probably more forgiving, otherwise you would run into the same problem in other programs.

Out of curiosity, what sort of device generates this messages? Is it a commercial available device or developed for your own use?

Regards, Henk

Hi Pascal,

UTF-8 is an invalid value for Content-Transfer-Encoding in an email message. Valid Content-Transfer-Encoding values are 7bit, quoted-printable, base64, 8bit or binary.

If you want to specify UTF-8 as the character set in an email, you can use the Content-Type, for example:
Content-Type: text/plain; charset=UTF-8

Regards,
Henk
