When using "with-open-file", what are the possible values of 
"external-format" (besides :default) under CMUCL and SBCL?

Is there an equivalent to Clisp's make-encoding in those implementations?

I'm still clueless after hours of searching.

There are no other interesting values for external-format under CMUCL.

SBCL's external format support is deliberately not yet documented or
fully exported, because it's not complete; in particular, certain
necessary things such as newline conventions and byte-order-mark
support are not implemented.  However, assuming you haven't disabled
the Unicode character set support, you can have anything that is
present in any of the CARs of the SB-IMPL::*EXTERNAL-FORMATS* list,
which as of today is
