Okay. Then we need to fix pg_get_encoding_from_locale to distinguish
"I don't know the locale's encoding" from "I know the encoding and it's
SQL_ASCII". I'm inclined to make it return -1 for the former,
which is a bit ugly but should be safe. The alternative is a separate
boolean output, which seems uglier. Comments?
