Reproduced and filed as [ticket 473][1]. [1]: https://abcl.org/trac/ticket/473 -- "A screaming comes across the sky. It has happened before but there is nothing to compare to it now."

Fixed with <https://abcl.org/trac/changeset/15386> aka <https://github.com/armedbear/abcl/pull/304>. There is still probably a bit of wonkiness with reading unicode, and I have noticed that FLEXI-STREAMS fails some tests, but at least FILE-POSITION should be expected to work. Thanks for the succint bug report! -- "A screaming comes across the sky. It has happened before but there is nothing to compare to it now."
