Okay, what's the width of U+F001? U+1EFA? The first is private use, and
the second hasn't been defined yet, but quite possibly will. The Unicode
standard at the least encourages Unicode conformant programs to deal with
unknown characters, requiring it in some cases (C10). Unicode is an open
repritore. Applications don't nessecarily know the behavior of all
characters.
