NONE only means store the bytes accepted and return them as is, and if a connection character set is specified, try to convert the stored bytes to that character set. It does not mean or assume ASCII at all. It just happens that most (all?) Firebird supported character sets (including UTF-8) use ASCII as the base for the first 128 characters.
