- Local encodings other than UTF-8 are not supported, and SQLSRV_ENC_CHAR only supports ASCII characters with ASCII code of 0 to 127.
## Known Issues
- User defined data types and SQL_VARIANT.
- Binary column binding with emulate prepare ([issue#140](https://github.com/Microsoft/msphpsql/issues/140) )
- Linux
- The following features are not supported with connection pooling:
- PDO is only supported with unixODBC 2.3.1.
- Unicode connection strings
- sqlsrv_server_info and sqlsrv_client_info return false
- In certain scenarios a generic error message maybe returned instead of a specific error when pooling is disabled
- When retrieving data from columns with a data type of XML, varchar(max), nvarchar(max), or varbinary(max) no data maybe returned or the data maybe truncated depending on the length of the data in the source table.
- When pooling is enabled in Linux or macOS
- unixODBC <= 2.3.4 (Linux and macOS) might not return proper diagnostics information, such as error messages, warnings and informative messages
- due to this unixODBC bug, fetch large data (such as xml, binary) as streams as a workaround. See the examples [here](https://github.com/Microsoft/msphpsql/wiki/Features#connection-pooling-in-linux-and-mac)
