I am getting a few of this type of error only coming from Windows machines, does anyone know how to sort this out?

ProgrammingError: ERROR: invalid byte sequence for encoding "UTF8": 0xa3 HINT: This error can also happen if the byte sequence does not match the encoding expected by the server, which is controlled by "client_encoding". insert into departmentplanning (planningcategoryid, taskid, subtasks, moneval, timescale, budget, success, subjectid, teacherid) VALUES (1 , 186 , 'Identify suitable tasks and activities for all G+T pupils and students ' , 'ADE- liaise with HS and GE' , 'JUL08 on' , 'SOme activities could be bought in ~£50' , 'All G+T pupils and students given opportunity for enhanced work' , 1787, 41 )
