I cannot reproduce this, and I don't see how this would be possible,
since encoded-string-description is only ever called for the result of
encode-coding-string, which must be a unibyte string.

This seems to be a very old build of a development version; do you
still see this in the current code?

More information was requested, but no response was given within a
month, so I'm closing this bug report.  If the problem still exists,
please respond to this email and we'll reopen the bug report.
