No, indeed you can't. In many ways, this is a similar situation to the
8/16/32-bit libraries. In principle, it probably would be possible to
have one library that switched dynamically at runtime between 8/16/32,
but it would be complicated, and performance would suffer. Given that
most applications use only one width, we decided to have 3 separate
libraries. My feeling is that the same is true for EBCDIC/Unicode.
