It seems to me that the problem here is that MacOS has a non-conforming
implementation of zip.  My first suggestion would be to fix that problem.

On the other hand, there is a large amount of redundancy in the UTF-8
encoding and if you only need to distinguish between Cp437 and UTF-8 you
could determine the encoding correctly in almost all cases.  Any valid
UTF-8 sequence which is not ASCII7 has at least two adjacent byte >0x7F
with the final one > 0xBF.  The simple rule would be: if the string is
valid UTF-8, process it as UTF-8, otherwise as Cp437.
