Issue with Displaying Special Characters in EML Documents

Hello Doconut Team,

I’ve encountered an issue with the display of EML documents. When I open MSG documents containing characters like “ä”, “ö”, or similar special characters, everything works fine. However, with EML documents, these characters are not displayed correctly, and instead, a question mark appears.

I’ve attached screenshots that illustrate the problem.

Could you please assist me in resolving this issue?

Thank you in advance!

Thank you for reaching out. To better assist you, could you please provide the following information?

  2. Could you also specify the version of Doconut you are using?
  3. Additionally, could you please send an example EML file where the error occurs?

Once we have this information, I will be able to provide you with the appropriate assistance.

Hi,

I am using version 4.8.1 of the .NET Framework and version 25.1.0.0 of your Document Viewer. Currently, I’m unable to attach an .eml file. Is there another way I can send it to you?

Best regards,
Leon Ramm

Our system doesn’t allow .eml files to be attached directly. However, you can compress the file into a .zip and upload it that way. This should work without any issues.

Let me know if you need any further assistance.

@lramm,

I am pleased to inform you that the issue with special characters not displaying correctly in EML documents has been resolved in the latest version of Doconut (25.3.0).

Now, you can explicitly define the encoding either for the entire email document or separately for the subject and body.

var emailConfig = new EmailConfig
{
    EmailEncoding = Encoding.GetEncoding("ISO-8859-1") // Set preferred encoding
};

Alternatively, if you need more granular control, you can set the encoding separately for the subject and body with SubjectEncoding or BodyEncoding properties.

This will ensure that special characters like “ä”, “ö”, and similar symbols are correctly processed and displayed.

Please try this with the updated version and let us know if you encounter any further issues. We appreciate your patience and feedback!
