Yes, I suspect I will never need it ;)

Incidentally, the situation is that in a script that tries to guess a
file's encoding, it bombed on the file ".svn/empty-file" -- but why it
was going so far with an empty string was really due to a bug
elsewhere in the script, trivially fixed. Still, I was curious about
this non-symmetric behaviour for the empty string by some encodings.

Anyhow, thanks a lot to both of you for the great feedback!
