This is because you forgot to cleanup your installation when using
--disable-unicode : there is a stale directory of encodings left out in
lib/ecl-10.2.1 or whatever. I will add a bit more intelligence to the
function to avoid this problem.

No, it does not. It uses whatever encoding the OS has, but we have no way to
know which one. For that reason in that case no external format symbol is
supported except :DEFAULT The fact that it uses an I/O function called
latin1* internally is because it is just an 8-bit reading function and I did
not want to duplicate lines of code.
