     This option controls whether the ODBC cursor library is used. The ODBC cursor library
     supports some advanced ODBC features (e.g. block scrollable cursors), which may not
     be implemented by the driver. The following values are supported:
     <itemizedlist>
      <listitem>
       <para>
        <constant>PDO::ODBC_SQL_USE_IF_NEEDED</constant> (the default):
        use the ODBC cursor library when needed.
       </para>
      </listitem>
      <listitem>
       <para>
        <constant>PDO::ODBC_SQL_USE_DRIVER</constant>:
        never use the ODBC cursor library.
       </para>
      </listitem>
      <listitem>
       <para>
        <constant>PDO::ODBC_SQL_USE_ODBC</constant>:
        always use the ODBC cursor library.
       </para>
      </listitem>

     (<type>bool</type>)
   </term>
   <listitem>
    <para>
     Windows only. If &true;, UTF-16 encoded character data (<literal>CHAR</literal>,
     <literal>VARCHAR</literal> and <literal>LONGVARCHAR</literal>) is converted to
     UTF-8 when reading from or writing data to the database.
     If &false; (the default), character encoding conversion may be done by the driver.
