No.  I think it is a serious bug because that returned value
is a sub-char-table which should not be exposed to Lisp.

Actually, we can think that a char-table has a default value
for ascii and eight-bit-xxx.  It is the default value of the
char-table itself.  So, I now think that your idea of
returning the default value is good.
