error running query { [error: invalid byte sequence for encoding "UTF8": 0xeb 0x6c 0x20]

[df7cb]

If a user's ircname isn't valid UTF-8, we fail login using a non-helpful error message on the user's end: "An error occured submitting your information". Internally, it's "invalid byte sequence for encoding "UTF8": 0xeb 0x6c 0x20]".

The internet (brianc/node-postgres#906) says the database config would accept client_encoding, but that didn't work here. (The user reported sending the POST request, just not getting a response at that point. Not sure if the setting made any difference, though.)
