Driver unicode type

 · ODBC (or later) Unicode Driver A bit driver that: Supports all the features of an ODBC ANSI driver. Exports Unicode versions of all ODBC string APIs. Can store and process Unicode data on the data source.  · SQL Server clients are one of two main types: Unicode clients that use OLE DB and Open Database Connectivity (ODBC) version or later. Non-Unicode clients that use DB-Library and ODBC version or earlier. The following table provides information about using multilingual data with various combinations of Unicode and non-Unicode servers. To make this determination, the Driver Manager supports two ODBC environment attributes: SQL_ATTR_APP_UNICODE_TYPE and SQL_ATTR_DRIVER_UNICODE_TYPE, each with possible values of SQL_DD_CP_UTF8 and SQL_DD_CP_UTF The default value is SQL_DD_CP_UTF8. The Driver Manager undertakes the following steps before actually connecting to the driver.

A C Unicode data type is provided to allow an application to bind data to a Unicode buffer. The Driver Manager can convert data from a Unicode C type (SQL_C_WCHAR) to make it function with an ANSI driver. An ODBC or 2.x application will always bind to the ANSI data types. For optimum performance, an ODBC (or higher) application should bind to the ANSI data C type if the SQL column type is ANSI, and should bind to the Unicode C data type if the SQL column type is Unicode. In this case, the driver converts from the client encoding to UTF, which can represent all Unicode characters. Furthermore, the target column or parameter on the server must also be either a Unicode type (nchar, nvarchar, ntext) or one with a collation/encoding, which can represent all the characters of the original source data. For avoiding data loss with output parameters, specify a Unicode SQL type, and either a Unicode C type (SQL_C_WCHAR), causing the driver to return data as UTF SQL_ATTR_DRIVER_UNICODE_TYPE (): The DataDirect driver manager gets the value of this attribute from the driver to know which unicode encoding is supported by the driver's wide functions via a call to SQLGetEnvAttr (). SQL_ATTR_APP_WCHAR_TYPE ().

NFC is the preferred way of encoding text in Unicode under Linux. By default, they use the character set specified in the HTTP content type returned by. FireDAC Unicode handling depends on: the version of Delphi being used. the client character set - UTF8/UTF16 or ACP compatible. the DBMS client / driver.
