Some import/export of courses failing with "code converter not found (ASCII-8BIT to UTF-8 with xml_text)"

[breiter]

Summary:

I have several logged course import failures. These all have the message "code converter not found (ASCII-8BIT to UTF-8 with xml_text)". I also have anecdotal reports that some students cannot export content. We are using s3 as the storage back-end. The failure happens within the S3 client.

Thanks for your help.

Steps to reproduce:

1. Attempt to import a .imscc file into a new course
2. User will get a message "there was an unexpected error. please contact support"
3. There is a corresponding error logged in public.error_reports with a stack trace failing in the AWS gem

Expected behavior:

Import and export of content should succeed.

Actual behavior:

Fails with an exception.

Additional notes:

We are using release/2024-07-17.337.
