I think it's pretty clear (at least to me), that such functions do
not belong in the normal path.  I'd be open to considering them as a
fallback attempt to read existing data (as opposed to generating new
encrypted data), but find Andy's argument about nonpredictability
(combined with David Woodhouse's enumeration of the various cases
and the minimal utility of such conversions) to be fairly
compelling.  That is, I am also against the use of functions that
depend on the current process's locale in libcrypto.  (I phrase this
slightly differently, in that functions which take an explicit
locale to use might still be okay, but are not really portable
enough for us to use, AIUI.)
