--- Comment #3 from Conrad Meyer <cem at freebsd.org> ---
Well, ok, these are the relevant dirents:

00000040  42 69 00 6f 00 6e 00 22  21 00 00 0f 00 72 ff ff  |Bi.o.n."!....r..|
00000050  ff ff ff ff ff ff ff ff  ff ff 00 00 ff ff ff ff  |................|
00000060  01 41 00 6c 00 69 00 65  00 6e 00 0f 00 72 5f 00  |.A.l.i.e.n...r_.|
00000070  20 00 49 00 73 00 6f 00  6c 00 00 00 61 00 74 00  | .I.s.o.l...a.t.|

It's a two-part LFN, in reverse order.  The bytes from 0x41-0x4a are
"ion\U2122\0".  \U2122 is "Unicode Character 'TRADE MARK SIGN' (U+2122)."  The
8.3 encoding is in a 3rd dirent:

00000080  41 4c 49 45 4e 5f 7e 31  20 20 20 10 00 31 5d 19  |ALIEN_~1   ..1].|
00000090  61 4a 61 4a 00 00 c2 19  61 4a 06 00 00 00 00 00  |aJaJ....aJ......|

"ALIEN_~1.   ".
