Like most problems rooted in POSIX (more fairly, in implementation
dependencies), it's not a problem amenable to elegant solutions.  The
data is conceptually a human-readable string, and therefore should be
representable in Unicode.  In practice, it normally is, but there are
no guarantees.

IMO, in this kind of situation it is best to raise the exception as
early as possible to preserve the context in which it occurred.

I have no objection to providing a library of handlers to implement
the strategies you propose, just to making any of them a Python core
default.
