    Research direction

    Start with the attached ERROR_folding_in_EmailMessage.py reproducer and the Python email component; confirm how EmailMessage folds UTF-8 content around a comma. The work is done when the missing whitespace is consistently present after folding and the reported behavior is covered by a regression check.
