No, it won't include Unicode, because it very clearly says "C locale"
right up there.

The problem is, it is *not possible* to extract the set of characters
out of an arbitrary locale.  The locale interfaces simply are not built
to allow it.

You can do it in the C locale, simply because the C locale is a known,
fixed quantity that you can hard-code.  You can't do it in any other locale.
