Need to remove \u0000 and Unicode surrogate pairs. \u0000 is not allowed in Postgres. JSON may contain UTF-16 sequences that is more than 16 bits, e.g. "\uD83D\uDE02" = "😂". These pairs are called surrogate pairs. They are converted into single character in Postgres JSONB storage. So Postgres don't accept one single dangling surrogate code point (they are actually invalid). But somehow these invalid code points appear in JSON...
