The problem is that UNIX VI sets the most significant bit when
the '%' meta-character is expanded.  Csh and sh strip
the data to 7-bit ASCII and hence there is no problem.
Ksh doesn't, hence the lookup fails.

This was one of the things we noticed when we did PC/VI, but
couldn't figure out any good reasons why VI did this.  Among
other reasons why we didn't do this was that DOS's command.com
isn't wild about setting the MSB either.
