Thanks a bunch to you and thenickdude for the test command and config to change.

I have an old VPS that isn't worth trying to update to a newer OS image, because I'm already (slowly) migrating things off of it before the current paid-up term expires, but it definitely won't get the newer glibc. Disabling the vulnerable character encoding works for me, since no legitimate user of the server will need these conversion pairs.
