Thanks. But I fear this needs some explanation; e.g. why does changing the base
from 8 to 12 (or 10 or 2) make that fail (and even fail in different ways)?
Why need hte base definition at all? And what's the semantics of the '\\' in
this context; printf --man seems to not explain that? Mind to elaborate?
(Also still interested in the question why plain printf "%c" doesn't work for
that purpose.)
Thanks again.
