UnicodeEncodeError attempting to send sales report

[dalers (Dale Scott)]

Hi all, I get the following error when attempting to email a sales report using either the Desktop client or sao, so I assume the error is related to the server environment, possibly a missing Python module.

Can anyone point me in the right direction?

Thanks,
Dale

Thank you @ced, it appears I had inadvertendly used a non-ascii character in the party contact email address. I re-typed the email address and now email is sent correctly.

I had speculated the issue was likely caused by copy/paste performed from Tad (a CSV file viewer viewing my master customer CSV), and pasted into a Party contact. The pasted string has quote characters around the email address and CR at the ending, and I assume I left a quote or CR in the string when it was saved. Testing though shows the contact cannot be saved if either quote character or the CR is in the contact value (value fails validation), so the root cause remains unknown.

However, it can’t be denied that the issue did not re-occur after re-typing the email address using the web client.
