Summary
ln: rejects non-UTF-8 source filenames in target-directory mode
Details

In target-directory forms (ln SOURCE... DIRECTORY), ln rejects source paths with non-UTF-8 filename bytes, while GNU accepts them. Breaks GNU compatibility for byte-oriented filenames on Unix filesystems.

PoC:

name=$(printf 'bad_\377'); mkdir dst; : > "$name"; ln "$name" dst
# GNU: exit 0, creates dst/bad_\377 ; uutils: exit 1, dst empty
