Hello, When I try to save my script file before closing the R console session I get this error. Error: invalid input 'C:\Documents and Settings\xxxx\xxxx\datafile' in 'utf8towcs' Does anyone know what can cause this error? I use the RGui (R verison 2.14.0) in Windows and the problem appears when I try to re-save the script file. Using Save as and rename it works. Kind regards, Marine Andersson
