If one can't depend on the order of evaluation, the the source encoding has to become a pragma that is preprocessed. The reader could probably preprocess the file looking for where the text "coding: XXXXX" appears within a comment in the top dozen lines of a source code file. Or perhaps a line that is explicitly ";;;; #pragma coding: XXXXX" in the top few lines of a file.
