Yes. That’s because I yanked the wrong charset from charset.h when porting
the code from XEmacs, and the attempt to create two-dimensional character in
JISX0201 fails, as it should, since JISX0201 is a one-dimensional character
set.
The code as intended, doesn’t trigger the message. As it was written, to my
discredit, it did.

This function is about transformation from an external format to the
editor’s internal format. Which is a big part of what coding systems do. So
some parallels in our approach is reasonable.

Perhaps, indeed.
