I object, but don’t have time to respond further right now. There are existing implementations where, by default, source files are assumed to be encoded with some EBCDIC code page. I don’t want to break those implementations, nor impose the significant burden such a change would place on users of those implementations.

This is (another) tangent to the original question. Source file encoding has nothing to do with execution encoding.
