How to set UTF8 in a lstlisting? (Error received)

I just solved it in using

  inputencoding=latin1

I hope it can help some in the same case than me.

listings cannot handle UTF8-characters. Search in the docs for the keyword literate. Then you'll see how UTF-8 characters can be mapped to TeX commands, eg ü->\"u: \lstset{literate={ü}{{\"u}}1}

I solved adding texcl=true to the \lstset configuration.
