function Connection::sqlFunctionLikeBinary

SQLite compatibility implementation for the LIKE BINARY SQL operator.

SQLite supports case-sensitive LIKE operations through the 'case_sensitive_like' PRAGMA statement, but only for ASCII characters, so we have to provide our own implementation with UTF-8 support.
