German umlaut encoded incorrectly using ProcessAttachments



An email is added to a work object as an HTML attachment. When the email contains diacritic characters (for example, ü (umlaut)) and the email charset is specific to ISO-8899-1, diacritic characters do not display correctly when viewing the HTML attachment.

Steps to Reproduce

  1. Configure a new Email Listener to create work objects on receipt of an email.
  2. In the associate Service Email rule, in the Request tab, select 'As HTML Attachment' to add the email to the work object as an HTML attachment.
  3. On the sending email client, set the email charset to ISO-8859 or equivalent (Outlook options > Advanced > International options: Preferred encoding for outgoing messages = Western European (ISO)).
  4. Send an email to the listener address. Ensure that the email body contains a 'ü' character.
  5. In the application, open the newly created work object.
  6. Open the attachment. The ü character displays as ü.


A defect in Pegasystems’ code or rules.

The email content was processed using UTF8 encoding regardless of the charset specified in the email.
