After modifying pypyodbc.py I've managed to overcome this issue only by 
changing line:

SQL_VARCHAR         : (str,                 lambda x: x,                
SQL_C_CHAR,         create_buffer,      2048  ,         False         ),

to

SQL_VARCHAR         : (str,                 lambda x: x,                
SQL_C_CHAR,         create_buffer,      2048  ,         True          ),

I've also changed this for SQL_WVARCHAR. Now it's working.

Did I fix this right, or was that False value right and I should overcome this 
differently?
