Oh, well, oops.  Just convert it twice.  

$ printf '%s\ngo\n'     \
        'SELECT name,
                content,
                cast(cast(content as nvarchar(40)) as varbinary(40)) as
HexContent 
        FROM tblite m WHERE  id = 1317' \
| tsql -S$S -U$U -P$P | hexdump -C

The idea is to let the server show you its own hexdump, if you will.
Example:

$ tsql -S$S -U$U -P$P
locale is "C"
locale charset is "646"
1> select N'hello', cast(N'hello' as varbinary(40))
2> go

hello   680065006c006c006f00
