Forbidding them seems reasonable to me; the only catch is that it is
the first step toward making a ton of individual decisions, some of
which will be wrong.  Better than getting them all wrong, of course,
but not better than postponing.  (I don't mean "ban all unicode
characters"; I do mean to ban far more of them, or to use a
site-specific incremental whitelist, or both.)
