identify mail attachment as utf-8 and convert it into iso-8859-1

[Former Member]

Hi,

in email sender I receive mails. Each mail has one attachment. The attachment may be encoded in iso-8859-1 or utf-8. If an attachment is in utf-8 then its content shall be converted to iso-8859-1.

Can this be achieved with a module or by any other means?

Any help is appreciated

If you do not know, if an attachment is UTF-8 or not, you need to write an adapter module to identify the codepage and do the conversion.

In standard you have to make sure that all email attachments have the same codepage.

Hi,

thanks to Mario for the pointer to the document. It describes a solution (with the MessageTransformBean) how to perform a codepage conversion when the codepage of the origin is clear.

However, this solution can not be applied for this case where only a few of the messages contain attachments that are encoded in UTF-8.

However, I have tried the TextCodepageConversionBean in conjunction with the PayloadSwapBean because the MIME type of the attachment is always text/plain. My configuration is as follows:

localejbs/AF_Modules/PayloadSwapBean Local Enterprise Bean TRANSFORM

AF_Modules/TextCodepageConversionBean Local Enterprise Bean 1

sap.com/com.sap.aii.adapter.mail.app/XIMailAdapterBean Local... mail

TRANSFORM swap.keyName payload-name

TRANSFORM swap.keyValue MailAttachment-1

1 Conversion.charset iso-8859-1

Expected was to get the attachment in XI using iso-8859-1. Instead the attachment is still in UTF-8. Moreover XI changed the first two special characters of the attachment (looking like yp) to four other special characters

Can anyone help?

Best regards

Markus
