Well, a simple search-and-replace operation can change that, so it's
really not important what you *type* but what you *see* as soon as the
document gets stored.

For our German wordlist we did a lot of experimentation, and the
middle dot serves our purposes quite well.  I certainly don't want to
see a caret instead.
