[armedbear-devel] encoding issues with ABCL

[Faré]

Dear ABCL developers,

it looks like ABCL is not doing the Right Thing with respect to
LOAD's :EXTERNAL-FORMAT argument, instead reading everything with
some dubious default from the environment. Can you fix it?

For instance, in Robert Golman's test below,
the file is read as MacRoman.

Please check COMPILE-FILE too in case it has the same bug.

Done.  I'm afraid the results are Greek to me.  Or would be if I could
get ABCL to print non-ASCII! ;-)

These two expressions fail comparison with EQUAL:
