Comment (by karsten):
I'm still unclear what you refer to. I believe we're now accepting those
descriptors with non-ASCII country codes in extra-info descriptors that we
rejected earlier. What case do you have in mind where we're not accepting
descriptors because of ASCII conversion failures? Note that we need to
perform some basic checks and computations to parse the descriptor
publication time, find out the descriptor digest, etc., so that we can
store it. Part of the requirements are an ASCII string at the beginning
and the end of the descriptor that tells us what part to compute the
digest of. If those are not ASCII, we cannot process the descriptor. And
if anything in between is not ASCII, we shouldn't complain, well, after
applying this patch.
