Using Samba 4.15.13 (from Ubuntu), I can see folders with names like 猎罪图鉴, but I can't access them. Looking at the wire traffic the SMB create request succeeds, but the subsequent find request fails with STATUS_OBJECT_NAME_INVALID. After some digging in the source I found that changing `mangled names` from the default `illegal` to `no` made the directories accessible; the mangler seems to be choking on the filenames. Is this expected behaviour? From my limited understanding I would have expected "mangled names = illegal" to handle all sorts of filenames. Thanks for your time looking at this!
