Or is it that when MB_CUR_MAX!=1, you really shouldn't "check whether a byte
is printable"? It doesn't make much sense to me: even if 0xA6 or 0xA7
appear as a byte in a BIG5 character, there is no guarantee that D8A7, say,
is a valid BIG5! So it's neither "printable" nor "unprintable"...

I think so.
