Hi @ewhanson,
please excuse my late reply.
I finally managed to convert the latin1 characters in our database to UTF-8 characters. I did not use the method mentioned above, but instead used the following SQL command and executed it for each affected table in the database.
SQL command for the table email_templates_default_data
:
UPDATE email_templates_default_data SET
subject=convert(cast(convert(subject using latin1) as binary) using utf8),
body=convert(cast(convert(body using latin1) as binary) using utf8),
description=convert(cast(convert(description using latin1) as binary) using utf8)
WHERE 1
This method took a few minutes, but was effective and did not produce any other errors.
Kind regards,
Michael
