Before we all go changing stuff (outlawing constructs, throwing warnings,
change meaning, whatever else has been suggested), does anyone have to
actual examples of code (that is, real code, not a constructed cases in
a theoretical scenario) that doesn't behave as the programmer intended,
and is caused by the ASCII-EBCDIC differences? Any bug reports? 

In other words, is there an actual problem that needs to be tackled?
