I can't reproduce this problem for the .el.gz case (indeed, I think
it's specific to byte-compiled files).

I think the problem lies between load-with-code-conversion and
eval-buffer, so it dates back to the introduction of
load-with-code-conversion, which IIRC predates the internal use
of Unicode.
Fixing `eval-buffer' so that it skips bytes when it sees #@NN is tricky,
so the best fix is probably to change load-with-code-conversion so that
(if the file is byte-compiled) it saves the buffer to a temp file and
passes that to `load'.
