[Qgis-user] configuración otb y grass

[Rafael Torres]

Muchas gracias Don,

Cambié los nombres de las carpetas para que no tengan ese carácter "ó" y parece que funciona ahora.

I think \xf3 is the ascii code for ó as seen at http://daleswanson.org/ascii.htm

Maybe the algorithm is having trouble interpreting that character if it's in any of the file names or the path to those files.

Worst case, you would have to remove that from all your filenames, but maybe it can be fixed by adjusting the operating systems default encoding that supports that character?

Unless someone knows that this limitation is part of python or QGIS?
