In one sense, yes: they can handle 8-bit data. In fact, they can handle
arbitrary binary data. In another sense, no: they do not treat all 8-bit
data as printable, even when the display will interpret them as Latin-1
or whatever. Unfortunately, Unix does not provide a way to find out
what characters are printable on a particular display device, so we have
to choose in the source which characters zsh will treat as printable.
No choice can be right for all displays; the current choice is a safe one.
The bug is in Unix; please send the bug report to K.Thompson and
D.Ritchie, twenty years ago. This bug will be fixed in a future OS[1].

[1] If I ever find the time to write the OS I've been planning, this is
one of the things that will be fixed. Character set and printability
are a function of the tty.
