There are three problems with this.
1. Currently unvis(3) can always reproduce original string regardless
of current locale setting. But above proposal make it impossible.
2. If \xHHHH means a wchar_t value, then it is not portable at all
(for example, there are at least two major ways to represent
multibyte EUC character as wchar_t).
If \xHHHH just means multibyte sequence, it's better to just use
current format of vis(3), IMHO.
3. How does unvis(3) handle \uHHHH in non-unicode locale which doesn't
have any corresonding character with the \uHHHH?
My current opinion is it's better to just leave vis(3) and unvis(3)
as is. :-)
