Hi Luis, Today we've been working on ABCL being able to compile and load BABEL; actually, it could do that already, but didn't work with BABEL-TESTS. We've committed some fixes which handle reader issues uncovered by the library, but we're now stuck: there's a bit of code commented out on CCL. It seems we're running into the same problems as CCL, due to strictness of interpretation of code points. Could you mark the #-ccl section in tests/tests.lisp as #-(or ccl abcl)? That solves our problem with the #\udcf0 code point. Thanks in advance! Bye, Erik.
